Please email [email protected] with any questions.



  • Maintain Social Distance. We encourage camaraderie between teammates and other competitors, but at 6-feet apart!
  • The first session that you climb the problems each week, you must submit your online scores! Attempts from later climbing sessions will not count!
  • Climb any problem in the week's new bouldering set (the tags will not have a grade and will say Bouldering League with a number). Mark down the climbs you have completed, and mark whether it was a flash or not.
  • A climber's top 5 climbs will be scored and the top 3 teammates' scores will be recorded for that week.
  • Go to to submit scores after your session. All scores must be in for the week by 6:15p on Sunday. You can use your phone to enter scores.
  • Paper score sheets are one per person / per week. Please drop your paper score sheet at the front desk before leaving. Remember to log your climbs before! Paper sheets are just used as backup.
  • No SANDBAGGING. Set your honest handicap. A handicap is defined by the hardest grade you can consistently climb in one session.
  • Individuals can climb on any league day during the week. This means that you may climb with your team each week but it is not required.
  • No substitutes allowed.
  • We will be requiring a witness to initial your climbs. Please be honest with your scores!
  • Try hard!


  • Scoring is normalized by your handicap (which is decided by you), which may be adjusted during the competition.
    •  Example: A climber with a V2 handicap climbing a V2 graded problem will receive the same amount of points as a V10 climber climbing a V10 graded problem.
  • Handicap Adjustment: As you progress and improve throughout the competition, your handicap will be increased accordingly.
    • Example: A climber with a V2 handicap sends multiple V3 problems, their handicap will be bumped up to V3.
  • Flashing will earn you extra points, and climbing harder than your handicap will also give you a higher score.
Notice: route grades will not be presented during climbing nights and the scoring is weighted progressively more each week. How mysterious!



How can I sign-up?
Either online or at the LAX Front Desk.
How much does it cost?
$64/team ($16/person) during early bird registration (10/08 - 10/22)
$80/team ($20/person) for regular registration, (after 10/22)
How many people to a team?
Four. The top 3 teammates' scores are recorded each week.
What if I don’t have a team?
You may sign up as a free agent. We will assign you a team!
Do I need to climb on a specific day/night each week?
New rule alert! Teams do not have to stick to climbing on the same night each week. Weeks run Tuesday at 5pm until closing on Sunday. You are welcome to climb on any day. You don’t have to compete on the same day as your team.
Can I climb on the new Bouldering League problems before my chosen climbing session?
Absolutely not! The first session you climb on the routes, you must submit a scorecard! If you are caught submitting scores after trying the problems multiple days, your scores will not count that week!
Must I attend every week?
No, but without you competing each week, your team will suffer.
Can my team have substitutes?
Nope! No substitutes, sorry.
How does the scoring work?
Scoring is normalized by your handicap, which may be adjusted during the competition.  You can read more about scoring on the 'Rules & Scoring' Tab on this webpage!
Wait, what is a handicap?
A handicap is your hardest grade that is consistently climbed during regular sessions.
Do the first week's scores count?
Yes. All weeks of Bouldering League will count toward your score. (This is different than in the past!)
Will there be 5 climbing days during finals week?
Yes. Finals week will run 11/16 - 11/21. There will be NO “combined” finals night for this season of Bouldering League. The winners will be announced in a hybrid meet-up on the evening of 11/21.
I'm not a member, can I participate in Bouldering League? 
Bouldering League is open to members, punch holders and guests! Guests can climb on one Bouldering League day each week for a discounted day pass rate of only $18.


  • Each participant will receive a t-shirt! The T-shirt is unisex. No tanks this season.
  • Prizes are given out on finals night for best team name! Please keep names to an appropriate standard.
  • Finals night is happening in person and virtually. If you are attending virtually, prizes will be at the Front desk for pickup the following day.
  • Bouldering League is a fun, inclusive community event! It's our chance to climb together in a team setting, while seeing progress in climbing each week and supporting others!
  • New Climbers: Check out this blog post on climbing terms to help catch you up to speed with the lingo!
