Onsight Bouldering League

Onsight Bouldering League

The fall season is so close that we can already smell the crispness of the air and feel the cool sandstone on our fingertips. We want you to get this bouldering season started off right! We are bringing you all something super duper exciting to get you strong, keep you motivated, and help you reach your climbing goals before the end of 2016. Onsight Rock Gym is proud to kick off our very first Onsight Bouldering League (OBL). It’s going to be pretty much the coolest thing since sliced bread so be sure to please read on for all the information you need to get your OBL dream team started!! All ages and all abilities are invited!

Registration: September 1 - September 23

All teams MUST be registered (via online form below or in person) by Friday, September 23

Cost: $50 per team (Pay at front desk, due by first competition week)

League Play Begins: September 26

Competition Weeks: October 3, October 17, October 31, November 14, November 28

Onsight Bouldering League Championship Tournament: December 9


The 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 a different team each competition week. Battle it out for 5 competition weeks and the teams with the best win-loss records will go head to head in the OBL Championship Tournament!

Step 1: Form Your Team

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? Let us know and we’ll get you on one!

Step 2: Register Your Team

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 23rd. Once registered, be sure to “Like” our Facebook page to stay updated and check this website page regularly for scores, rankings, and announcements:

Step 3: How Competitions Work

OBL competition weeks are every other week for a total of 5 weeks: October 3, October 17, October 31, November 14, November 28. 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. Each team will be matched up with a different team to compete against each competition week and the team with the highest score will earn a win for that week. 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 9th where teams with the best win/loss records will compete head to head in a bracket-style elimination competition. The two best teams at the end of the day will compete for the big win! The prize? It's going to be a secret won't be disappointed. 


Scoring: The Handicap System

Each team member will receive points for the top 3 problems completed during their competition day:

  • 10 points for redpointing handicap grade

  • +3/-3 points for each grade above and below handicap grade

  • +3 points for flash

**Flash = Finishing the climb on the first attempt

Redpoint = Finishing the climb with two or more attempts

**For the purposes of this competition, a flash will be considered the first attempt of a problem on competition day. Some of the OBL designed problems will be chosen from the existing problems already on the walls, so it is likely that competitors prior to the competition week, will have previously tried the boulder problems. So a competitor can “flash” a problem they had done on a previous visit, and this is allowed.

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 handicap grade. The handicap grade is the hardest grade you regularly climb.


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

  • Lucy Jo usually climbs V3, but once every couple of weeks, she gets a V4 = V3 handicap

  • Peter Piper climbs V8 once a week or so, but 1 year ago, he was crushing V10s = V8 handicap

  • Mary Poppins climbs V2 easily, but is intimidated to try V3s = V2 handicap, but will be adjusted to V3 if she is flashing all V2s on the first competition day.

Handicaps can change throughout the 10 weeks of OBL competitions, so don’t get to stressed out about what to pick. 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 go through a rough patch (we hope you don’t!) and can’t seem to climb at the same level you were before, we’ll adjust that as well.

Each competition week, the scorecard will have a certain number of problems designed for OBL, ranging from V0-V10+. The goal of each team member is to try and flash or redpoint problems at or above your handicap to earn the most points for your team. We’ll count the top 3 highest scores per team member. Each team member’s score will be added together for the total team score for that week. If your team score is higher than your assigned opposing team for that week, your team earns a win. At the end of the 10 weeks, the teams with the best win-loss records will be invited to compete in the OBL Championship Tournament.

Important Rules:

  • 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 severely punished.

  • 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.
