Onsight Bouldering League Championship Tournament: Friday, December 8


Onsight Bouldering League is a 10-week team competition that rewards personal achievements rather than climbing grades. Every 2 weeks, teams of 4 boulderers pick up score cards and tackle that week’s designated OBL boulder problems. Teams will be scored and compete against one another each competition week. Battle it out for 5 competition weeks and the teams with the best cumulative scores will go head to head in the OBL Championship Tournament! 


One team = 4 Boulderers (We highly suggest to have one alternate for weeks when someone plays hookie or drops out). Do not discriminate between gender, climbing ability, and age. All climbing levels are welcome. We will score based on a handicap system (explained below) so if you climb V2 and your buddy climbs V10, you can still be on the same team. Interested in joining a team? Email and we’ll do our best to help get you on one!


Got your team together? Great. Designate one person to register either online via the link below or at the front desk. Team members must be Onsight members, punch pass holders, or purchase a day pass for each visit. Registration fee is $50 per team (that's only $10-$15 per person for the entire 10 weeks!) All teams MUST be registered by September 29th. Once registered, be sure to “Like” our Facebook page to stay updated and check this website page regularly for scores, rankings, and announcements:


OBL competition weeks are every other week for a total of 5 competition weeks: October 2, October 16, October 30, November 13, November 27. Starting on Monday of each competition week, each team will pick a day to come in together as a team to climb the designated OBL boulder problems for that week. All team members need to be present to receive a scorecard. Teams are responsible for keeping track of what problems they climbed and handle their own scorecards. Please use the honor system. During non-competition weeks, we’ll set new problems, calculate scores, and post them online. After 5 weeks of competitions, we will host a OBL Championship Tournament on December 8th where teams with the highest cumulative scores will compete head to head for the big win! The prize? Each member on the winning team will take home a pair of Evolv Shoes! 


Each team member will receive points for all problems completed during their competition day:

  • 10 points for redpointing handicap grade

  • +3/-3 points for each grade above and below grades within your listed division

  • +3 points for flash

Flash = Finishing the climb on the first attempt

Redpoint = Finishing the climb with two or more attempts

Please note that you are allowed to climb on the bouldering wall during a competition week without your team present but are highly encouraged to stay off of the designed OBL problems. If you attempt any OBL problems during a competition week, without your team and scorecard present, you will forfeit your "flash" attempt on that problem. 

How the handicap system works:

Handicapping allows non-discrimination of gender, climbing ability, and age. Climbers of all levels and abilities can all be on the same team. This system rewards personal achievement while prioritizing fun and camaraderie. This system is fairly simple. When a competitor registers, they will designate their division based on the hardest grade they are able to consistently climb. Divisions are as follows:

  • VB-V2 = Novice

  • V3-V4 = Intermediate

  • V5-V6 = Advanced

  • V7-V10 = Open


  • Billy Bob usually gets up at least one V6 per week = Advanced

  • Lucy Jo usually climbs V4, but once every couple of weeks, she gets a V5 = Intermediate

  • Peter Piper climbs V6 once a week or so, but 1 year ago, he was crushing V8s = Advanced

  • Mary Poppins climbs V2 easily, but is intimidated to try V3s = Novice, but will be adjusted to Intermediate if she is flashing all V2s on the first competition day.

If you need help in determining your handicap, ask a staff member for help. Handicaps can change throughout the competition, so don't worry too much about being perfect with your self-assessment. If you suddenly get stronger (we hope you do!) and start regularly climbing a grade harder than your stated handicap, our scorekeepers will adjust your handicap. Likewise, if you feel your handicap should be adjusted, just email and we'll take care of it.

Each competition week, the scorecard will have a certain number of problems designed for OBL, ranging from VB-V10. These grades will not be displayed on the OBL labels. The goal of each team member is to try and flash or redpoint as many problems as you can to earn the most points for your team. Each team member’s score will be added together for the total team score for that week. At the end of the 10 weeks, the teams with the best cumulative scores will be invited to compete in the OBL Championship Tournament.


  • There are no do-overs during competition weeks

  • Four team members must all come together, on the same day, and climb OBL competition problems in one session. Scorecards must be turned in by the end of the bouldering session.

  • If you are using an Alternate Team Member, it must be stated at the time your team picks up the scorecard for that competition day.

  • No scorecard turned in for that week = 0 points

  • Scorecards completed based on honor system. Sandbaggers and cheaters will be expelled from this competition and banned from competing in future OBL competitions.

  • Only designated OBL problems count towards your score.

  • If a team member quits the league before completion of the 10 weeks AND there is no alternate for the team, another team member may be added in his/her place or the team may choose to continue on with one member short.
