The Onsight Sport League is a 9-week team roped climbing competition. Every 2 weeks, teams of 4 climbers pick up score cards and tackle that week’s designated OSL routes. A cumulative final team score will be determined after four competition weeks. The two top scoring teams in each division (Top-Rope and Sport/Lead) will advance to the OSL Championship Tournament and go head-to-head in the ultimate finals competition in flash format!

Step 1: Form Your Team

One team = 4 Climbers (We highly suggest that you have one alternate for weeks when someone plays hookie or drops out)

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

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 18th. 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 19, July 3, July 17, July 31. The 5th and final competition will be the OSL Championship Tournament on Friday, August 18th. 

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 set for that week. 16 routes (every grade 5.7 through 5.13a) will be set every 2 weeks with assigned point values. A send will result in that amount of points, with a flash yielding a 10% bonus. Attempts (falls) will be counted to break ties. 

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. As for the scoring, teams will have as much time as they want, but must compete all their climbs in one session as a team. Once somebody leaves the gym, their session for that well of competition is over. Participants will receive points for any and every route they send. Obviously, the harder routes are scored higher, but it'd be to the climber's benefit to complete as many routes as possible.

During non-competition weeks, we’ll set new routes, calculate scores, and post them online. Teams will accumulate points through the first 4 competition weeks.

After 4 competition weeks, we will host the OSL Championship Tournament on Friday, August 18th in flash format. The top two scoring teams in each division will advance and compete in this final tournament. 2 or 3 ultra-progressive routes will be set, both on top-rope and sport. Climbers will have one attempt on each route in their division. Scores will be based on high-points. Based on the scores from the final tournament (not previous competition weeks), a Top-Rope and Sport division team will be crowned champions. The prize? It's going to be a secret won't be disappointed. 


  • 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 severely punished.

  • Only designated OSL routes will count towards your score.

  • Please use the honor system and do not try out an OSL route until your team meets for each competition day.

  • If a team member quits the league before completion 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.

  • All team members must be present at the OSL Championship Tournament on Friday, August 18th in order to compete in the finals.
