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

Step 1: Form Your Team

One team = 4 Climbers (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.

Pick a Category: Top-Rope or Sport (Lead) Category. Anyone lead-certified must compete in the Sport Category, no exceptions.

Pick a Division: See "Scoring: The Handicap System" below to learn how to pick your division. We will score based on a handicap system so if you climb 5.8 and your buddy climbs 5.13, 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 $12.50 per person for the entire 9 weeks!) All teams must be registered by Sunday, June 17th. 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

OSL competition weeks are every other week for the first 4 competitions: June 18, July 2, July 16, July 30. The 5th and final competition will be the OSL Championship Tournament on Friday, August 17th.

Starting on Monday of each competition week, each team will pick a day to come in together as a team to climb the designated OSL routes for that week. All team members need to be present to receive a scorecard. Teams are responsible for keeping track of what routes they climbed and handle their own scorecards. Please use the honor system.

During non-competition weeks, we’ll set new routes, calculate scores, and post them online. After 4 weeks of competitions, we will host a OSL Championship Tournament on August 17th where teams with the highest cumulative scores will compete head to head 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 all routes 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

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:

  • 5.6-5.8 = A

  • 5.9-5.10b = B

  • 5.10c-5.11a = C

  • 5.11b-5.11d = D

  • 5.12a-5.12c = E

  • 5.12d-5.13b = F


  • Billy Bob usually gets up at least one 5.11b per week = D

  • Lucy Jo usually climbs 5.10b, but once every couple of weeks, she gets a 5.10c = B

  • Peter Piper climbs 5.11d once a week or so, but 1 year ago, he was crushing 5.12bs = D

  • Mary Poppins climbs 5.8 easily, but is intimidated to try 5.9s = A, but will be adjusted to B if she is flashing all 5.8s on the first competition day.

Handicaps can change throughout the 10 weeks of OSL competitions, so don’t get too 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 routes designed for OSL, ranging from roughly 5.6-5.13. These grades will not be displayed on the OSL labels. The goal of each team member is to try and flash or redpoint as many routes 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 OSL Championship Tournament.


  • There are no do-overs during competition weeks

  • Four team members must all come together, on the same day, and climb OSL competition routes in one session. Scorecards must be turned in by the end of the climbing 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 OSL competitions.

  • Only designated OSL routes 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.
