Sender One vs. 2020: A Look Back

Sender One vs. 2020: A Look Back

the content
Well, we’ve made it to the end of 2020 and maybe we can all agree that this year was not what we had in mind. It’s bizarre to reflect on what this year has been for Sender One. We could not have made it through this year without the strength and support of the climbing community, Sender One members, and our incredible staff. We won’t go into major detail as we look back on 2020 because let’s face it, who really needs to relive every moment this year has provided? Instead, we’re taking this moment to reflect on good news from the year and some of the hard lessons learned.

January & February

We hosted the 2020 Pan American Championships at Sender One LAX, qualifying Alannah Yip and Colin Duffy for the (now) 2021 Tokyo Olympics. Little did we know that this would be the last large international climbing event in the states for the entire year. What an honor it was to experience this!


Both Sender One locations were mandated to close for the first time as the rise of COVID-19 began impacting our local counties. At this point, we thought the closures would be short-lived. A real pandemic causing businesses to close and forcing us to stay inside, mask-up, and physical distance? Nah.

April & May:

Hello, at-home workouts, the Sender One online shop, and virtual yoga classes! With our locations still closed, we took action and got creative. While trying to maintain jobs and community engagement, we launched an online retail shop and provided virtual yoga and fitness classes. We even sold limited-edition Sender One hangboards, personally handmade by a few of our routesetters, and Sender One masks that were handsewn by another ultra-talented employee who is literally a knit-master. 

This was also the time many people and businesses, including ourselves, were reminded to reflect intrapersonally as the Black Lives Matter movement took rise over the killing of George Floyd (10/14/73-5/25/20), Breonna Taylor (6/5/93-3/13/20), and the many other unjustly deaths of Black individuals. We will always have a zero-tolerance for racism and understand that this fight for an equitable and just society is far from over. As we continue to learn from the collective community, we hope to always create ways to foster an inclusive and diverse climbing environment.


Sender One turned 7! Though we didn’t have our typical birthday bash, we were fortunate to reopen both locations during this month. It was interesting to reopen with new standard procedures, health protocols, and navigating through the so-called “new normal”. The amazing Sender One team really climbed together by getting the facilities ready to welcome back our members.

Also during this month, we held a virtual Pride Event, raised money for the NAACP Legal Defense Fund and Black Lives Matter, and kicked off our climbing camps. We were unaware that youth camps would become our main offering this year.

July & August:

We entered our second closure for both Sender One facilities after being open for a few short weeks. It was time to pivot our business even more so we went a little camp crazy while maintaining virtual yoga classes and running the online shop. Although fitness/climbing centers were to remain closed, youth day-camps were allowed to operate since they provided an essential service for working parents. Being stuck at home as a child can be hard, so we were happy to cultivate an environment for youth to connect through our summer camp, routesetting camp, and distant learning camp (COOL Camp).

September & October:

Sender One SNA got the green light to reopen! During this time, we held a couple of COVID-friendly community events, brought back our popular Bouldering League, and helped form the California Indoor Climbing Coalition. It felt great to bring the community together while uncertainty still loomed. We made sure to cherish and celebrate every moment - big and small.

November & December:

Sender One SNA reopened for 9.5 weeks. These weeks were filled with under-the-mask smiles and laughter, new climbs, new projects, new sends, and a lot of hand sanitizer. We were extremely saddened to re-close our doors again, but fortunate to carry on with youth camps and a virtual raffle for a good cause.

Looking back at this year, it’s easy to think about all the negative aspects. Don’t get it wrong, this year was extremely hard for us and many others. We have all just experienced a year that will forever change our lives. It’s important to take into consideration the different experiences of those around you and to take time to check in with loved ones. 

Sender One will continue to survive and thrive into 2021, but we are not leaving this year without acknowledging the difficult decisions we made, lessons we learned from, and changes we’ve adopted in order to safe-keep our future. So here’s to a year filled with challenges, growth, adapting, staying resilient, and endless gratitude.

Thank you to the climbing community, Sender One members, our phenomenal staff, and the families and friends that continue to support and be here for us. Lastly, Alice Kao (Co-Founder, CEO) has put together a letter for the community which you can find below.


See you in 2021!

Tips on Returning to the Climbing Gym

Tips on Returning to the Climbing Gym

the content

After months away from the climbing gym, it’s a good idea to ease your way back into crushing those projects -- unless you’re some super human that can climb V15 off the couch. With Sender One SNA open again and LAX following (hopefully) soon, we wanted to provide some tips on returning to the climbing gym.

TIP #1: Stretch before arriving at the climbing gym.

Because time is limited to 2-hour climbing sessions (for now), we suggest doing some stretching at home. You can refer to this warm-up video we made for our at-home iSWOLation workout challenge. Stretching prior to arriving at the climbing gym may help speed up your on-the-wall warm-ups so you can get to sending!

TIP #2: Be kind to yourself and your fingers/skin/tendons.

Take it easy! With the lack of consistent climbing over the past few months, our bodies need to readjust. Don’t overdo it because you may run the risk of getting injured. Listen to your body and rest when needed. You may be surprised at how quickly you will get your strength back!

TIP #3: Keep your mask up, covering your mouth and nose.

Out of respect and to protect yourself and others around, make sure to always mask up while inside. If you need to catch your breath and breathe in some fresh air, you can let the staff know that you’re stepping outside for a few breaths. The ONLY time a mask can be removed while indoors is to drink water or munch on a snack (between bites).

TIP #4: Come prepared to climb in proper attire.

For now, our showers and locker rooms are unavailable until further notice. We highly recommend coming to the climbing gym in your climbing attire so you can be ready to hop on the walls.


Bring your own refillable water bottle! Only the refill stations at our drinking fountains are available. We do, however, still provide an assortment of energy bars and beverages for sale to help fuel your climbing session!

TIP #6: Hang in there!

This year has been absolutely crazy. Bring on the socially awkward moments since we’ve all been stuck in our homes for 6 months and have forgotten how to act in the presence of other human beings. We love awkward and we will happily welcome you back with open arms, from a distance, with sanitizer and a thermometer in hand. Things are going to be different for a while, but we will continue to be here for you!

"On August 12, 2019 I had set out with some friends to do Mt. Russell, 14,094 feet. By then, I had been lead climbing at Sender One for nearly a year and felt extremely comfortable hitting class 3 and 4 terrains. I had also done Mt. Kenya (see previous blog here), which was class 4 and required rope and trad climbing.

In 2016, I got invited to a friend’s trip to Mt. Russell only to be dis-invited due to a fall-out.  To add insult to injury, my friend said that I did not have the skills to do Mt. Russell. I was outraged. How can my friend tell me what to do?  I was already top roping at Sender One for nearly one year. I had already done the big hikes: Mt. Whitney, Cactus 2 Clouds Trail, San Gorgonio, Santiago Peak and Mt. Williamson. How bad could Mt. Russell be? All I heard about was its scary knife’s edge that was one foot wide and that people could fall to their death on either side.

I shrugged my shoulders. I had never been afraid of heights or exposure. When I heard that one of my hiking friends, Peter, was interested I was keen to go.  Peter met this guy named George who also wanted to do it. George was very experienced, as he had hiked over 3,000 peaks since the 1980’s. It appeared that George wanted to get a permit with 4 people.  So I recruited a 4th person, Clark on a Facebook site called California Peaks. Clark had a solid climbing resume.

So the day came when Peter and I planned to drive to the Lone Pine visitor center to get the permits. When we arrived at the visitor center, it was 8:30AM and it had already been open since 8AM.  That meant that there were already people before us. The woman at the counter taught us to keep checking the website to see if anyone dropped out of their permits. If so, then we could take them and secure our spots.  She told us that there were no guarantees for the walk-in permits since we were also competing with people from other centers.

My friend was checking online for 15 minutes and then gave up. I felt disheartened that we may not be able to do Mt. Russell. I kept trying as if I were in a trance. Finally, after about 40 minutes, I found that 4 permits were available. I shrieked in excitement and we quickly made the reservations.

We met up with George and Clark later that day to discuss our schedule. Our plan was to get up at 4:30AM and start the Whitney Mountaineer’s route, and then turn off to the Carillon Pass and head up toward Mt. Russell. We slept in the truck at the Whitney portal, which was about 8,374 ft above sea level.

At 4:30AM, we met promptly at the trailhead. We started going at an extremely accelerated pace and I was becoming breathless. Despite that I had a caffeine gel to feel energized, I was slowing down. We had several stream crossings and it was extremely steep.  Plus, there were a few times we went the wrong direction and we needed to redirect ourselves. Sometimes George would wait for me, and other times Peter would. It seemed like Clark, who was in his mid 20’s, was a speeding demon.

When we got to Boy Scout Lake at 9:00AM (half-way point) Clark was concerned that we were going too slow and would not be able to return through the tricky sections of the route before dark. Clark suggested that I turn back since I could not keep up the pace with the group. I refused. George was saying that he could not go at my slower pace, and Peter was calling my pace “demoralizing.” I was more determined to prove them wrong.

It turned out that Clark and George raced ahead, and eventually Peter could not keep up with them and fell asleep. I was left behind, but I was yelling and Peter woke up to my cries. He had thought that I had turned around and given up. He was already dejected.  I told Peter that we still had an opportunity and that we could still do it. I said that it was early in the day and that we could take as many breaks as he needed. Eventually we found out that Clark and George had taken us on the wrong route again so we had to reverse our direction.  We had to go up through sand that slowed our steps. By 11AM, we were able to see Mt. Russell a mile away.

When we got to the ridge, we had a mixture of emotions. I was excited as I enjoyed rock climbing, heights and exposure. Peter was terrified because he was afraid of heights. We decided to set our packs down to shed weight. I led the way, and I could see where there appeared to be a path across the rocks. We had to go to the west peak, which was the tallest part of Mt. Russell. I felt like I was floating in air, as I sometimes had to trust that my hands and feet were touching a solid section behind a wall as I brought my body around it. Some parts were sketchy, and I felt at one point my grip loosen and the hair rising on the back of my neck. Sometimes it felt like we were bouldering. We saw Clark and George on the way back from the peak. I kept climbing and got to the highest point at 3:30PM.  I saw that there was a summit register. I called out to Peter in joy saying that he was close to the top. He immediately followed me, and laid down on the summit block.

Peter and I took some pictures and then we knew we had to head down this ridge before it got dark. I was very thirsty, as I had left my pack. I began sucking on snow, and Peter made fun of me because it probably had germs.  But I smacked my lips in satisfaction. He started sucking on snow too, and pretty soon, we were acting as if chunks of snow were precious pieces of watermelon.

When we got to our packs, it was a relief. I drank water from my pack and also had dinner. We started hiking away from Mt. Russell and then down the Carillon pass.  There was one point my pack was actually dragging me off the cliff so I had to make a decision to release it, otherwise I would fall off the cliff with my pack. I lost my phone as well.

There was a time when Peter went far ahead and I called out to him not being able to see him. After calling out many times, I began to cry thinking I was in the wilderness by myself. I was hoping someone would find me. I thought Peter had left me to die on my own. I was being dramatic but I was sobbing and feeling helpless. Finally, he came back to me and demanded to know why I was on the ground.I told him that I was crying.  

We continued to find our way back with our headlamps on. Unfortunately, the well-established trail would fade away when we reached the streams. Sometimes Peter thought we had to cross the streams to get back on the trail. Both times, I was really scared to get sucked into the rapids. My hiking boots and socks got seriously wet. I told Peter we should wait until daylight to find our way back. Peter was resigned to the fact and we laid on the ledge shivering and we huddled together for warmth.

The next morning, we still could not find the trail back. We had to call George (luckily Peter had 8% battery) left on his phone. George eventually found us and led us back through the stream in a way that had not been straightforward. It took us an hour to get back to our cars. 

If we were to do Mt. Russell again, we should have camped at Upper Boy Scout Lake, the halfway point at 11,500 ft.  Then we would have summited the next day, and then returned to our camp, and leave refreshed the following day. Mt. Russell had made me a better climber. When I go to the gym, I no longer get sketched out easily when I am afraid of falling on lead. I think about Mt. Russell and how I had almost lost my life when my pack went over the edge. I definitely think these outdoor experiences serve to enhance our experiences when we return to climbing indoors".

"My name is Amy and I have climbed at Sender One LAX since the beginning of 2017. My passion for rock climbing started when I took a Wilderness Travel Course (WTC) and climbed peak of 4377 ft. in Joshua Tree. It was then that I fell in love with rock climbing.

On December 28, 2018 I decided to rock climb up to Nelion (17,027 ft.) and Bation (17,057 ft.), peaks on Mt. Kenya. Mt. Kenya was ideal because it was the second highest peak in Africa at 17,057 ft and it required rope climbing to get to the summits.  I could have easily done rock-climbing peaks in the U.S. but I wanted an international adventure. I spent a total of 7 days hiking in Kenya.  

One of my practice grounds was Sender One LAX.  Since I have done top roping consistently for about 2 years, I decided to try lead climbing.  I took the lead climbing class at Sender One and became lead certified. Lead climbing at Sender helped me become more confident in my rock climbing abilities.

I did not know that the approach to Mt. Kenya’s rock climbing would take 2 hours from the Austrian Hut (15,700ft) on clumps of loose talus.  Nor did I know that I would be wearing my La Sportiva snow boots, which acted like “death traps” for my feet. I was told that when I got up to the second highest peak, Nelion, we would have to down-climb and cross a glacier field and use our ice axes and crampons, to get to Batian, the higher peak.  Unfortunately these snow boots were the only ones that fit my crampons. My snow boots however, were not ideal on rock as it made it very slippery. The only other shoes I carried in my pack were my climbing shoes. My snow boots made me feel like I was hauling 2 additional pounds on each leg.  

At 5AM, on December 28, 2018 after an early breakfast, we began the approach to the base of the mountain.  When we got to the start of our climb, it was 7AM. I was a bit cold changing into my climbing shoes. As I put my snow boots into my pack, I realized that they took up the majority of my 40-liter pack.  My water bladder was frozen, but luckily, I had about a liter of hot water stored in a thermos. My guide would be on lead setting up the cams and the bolts while I belayed him from below. Looking at the rock, the hand and footholds looked straightforward, I actually thought it could be possible to free-solo Mt. Kenya.   Little did I know that there were some tricky sections where I would fall. After my guide would set the route, I would tie myself in and climb up the rope and clean what he had done while he belayed me from above.  

Sometimes I had a difficult time understanding my guide so I had to have him repeat whether to “take” as there was one point he had been afraid of falling, and when he was all done setting up the route, I had to confirm with him that it was ready for me to climb.  The grade ranged from 5.4-5.8, and there were times I had to traverse to the side or down climb.      

When we had done the first 3 pitches, my guide asked me for the time.  I responded with 9:10AM.  He was concerned that we would not have the time to climb either peak. I frowned, as I did not want to fail. Determined, and probably a big mistake, I climbed faster only to fall 10 ft., flip upside down and hit my back against the rock.  Luckily, I was wearing my helmet, which protected me from concussing, and my pack cushioned my back from getting severely hurt. I decided to shed my layers so I wouldn't overheat. Since I could not fit my extra layers in my pack, I had to leave it on one of the pitches. I thought maybe it would not get too cold and the only thing I could fit in my pack was a thick long sleeved-shirt. At the time, I was only wearing one layer of pants and one shirt.      

My guide was surprised that I was able to get through the difficult sections in a reasonable amount of time. So he said Nelion was possible to summit, but not Batian which involved rappelling down, crossing the glacier and 5 more pitches.  So happily, we left our ice axes and crampons on another pitch since we would not be using them.  

We arrived at the summit of Nelion peak at 4:30PM.  Nearby, there was the Howell Hut where some people bivouac or spend the night before they continue to Batian. At that moment, I only had a thick long-sleeved shirt from my pack. 

The nightmare began as we started to rappel down 18 pitches while shivering violently as it had gotten really cold.  I asked my guide where my jacket and warm clothes were and he replied they were at pitch #9. We had a system where he would rappel down first, and then I would anchor myself and then set my belay device for rappelling. I consciously told myself that I had to make sure that I was doing things right since there was no one to check me once my guide was gone.  

As I rappelled down, I felt like dead weight as I was tired banging into the walls going down.  The scary part was that although we had our headlamps on, it was getting difficult to see clearly at night. I was crying because I was so cold, and my guide begrudgingly gave me his windbreaker to wear that reeked of cigarette smoke.  

Twice, we had gotten the rope stuck on the rock, and we had to pull down.  The scary part was that we could not see where the rope was caught and we had to trust that we could get the rope un-caught.  I used the bulk of my weight to pull the rope down, as I had run out of strength. We had finally gotten to the pitch with my warm coat but after putting it on, I was still a bit cold but I could not put my thermal pants on as my snow boots were tightly fastened and I had no energy to take them off.  

When we had finished rappelling, I was spent.  I could not walk in a straight line with my snow-boots and had to glissade down on the sand and rocks. I could no longer carry my heavy pack. My guide went to get my team to help carry my pack and guide me back to the hut, which was 2 hours away.  I waited for 3 hours in the cold and prayed that I would be alive the next morning as I pictured freezing to death. Around 3AM, my team got me and gave me warm water to drink. They brought my regular hiking shoes, and hiking poles so I could walk easily, while carrying my heavy pack. In the end, I gave them a big tip, and was grateful that I could get back to the hut and rest. I also felt very proud to have done this multi-pitch climb. I was also touched by the kindness of my team to come get me in the early morning. I was grateful to be warm again.

When I returned, I was ready to tell people at Sender One about my experience and encouraged them to take their rock climbing to a new level. I would like to encourage more foreigners to utilize reputable African guides because they really need the money. Since I paid an affordable rate with an African Company, I was able to tip their workers more.  For example, my cook was touched that I gave him a $140 tip as he could now spend more time with his family. I felt like my African guides gave me a wonderful experience, and I wanted to show them my gratitude by giving them a generous tip for their services."
