Central Rock - Harvard Square

Hours this weekend! Stay classy and cool!

BOULDER BASH is Back for the 4th year!!!

Starting Tuesday July 7th, Boulder Bash is a 5 week FREE boulder competition hosted by Central Rock Gym Harvard Square. More info below and at our Link in Bio!

Each week on Tuesdays as usual, the setting team will reset 1 section with new routes by 4pm. Competitors will log their hardest 3 ascents per week on a scorecard we will have available all summer at the front desk. CRG Staff will tally the scores, and the sum of these scores will comprise 1/3 of your Final Score. Scorecards must be turned in to the desk at the end of your climb daily, and we will store them until your next visit. Traveling for a week or so? We have you covered. After the final week of boulder bash we will drop your lowest or missed week.

On Saturday, August 15th, the setting team will do a larger reset for a Final Day Event, and participants will have only that day to log their hardest 3 ascents of this new set. This day is important to attend and will weigh more in determining your final score.

This event is an awesome chance to challenge yourself to climb your hardest and see what you’re capable of, while having some fun competing against others of a similar skill level!

Week 1 begins July 7th, scorecards will be at the front desk throughout the weeks just ask for one, and get crushing!

Weeks:
July 7th -13th
July 14th – 20th
July 21st – 27th
July 28th – August 3rd
August 4th – 10th
Boulder Bash Saturday August 15th – and awards following Boulder Bash!

How it Works
You will compete to send your hardest climbs, earning points in the process with the hope of out-scoring other competitors. Routes will be labeled with a point value instead of a grade.
Participants will earn points for each route they send, which they will record on the provided scorecard.
Sends must be verified by obtaining a witnesses’ initials on the scorecard.
Each route will remain active to score points on for at least 7 days, after which, those routes will revert to our standard grading and points can no longer be earned.
Participants are welcome to climb and track their points every day during the Bash.
