Climb for Ludovyk Charity Comp

On November 30th we’re having an in-house charity boulder comp! All proceeds of this event will be donated to route setter/coach Max’s family to help accommodate his nephew Ludovyk’s rare condition, Duchenne Muscular Dystrophy. $15 at the door (in addition to membership/day pass). Registration at 6pm.

We are so grateful to have so many great people in our climbing community and in KW. We have had A LOT of amazing prizes donated for our Climb for Ludovyk charity competition on Nov 30th. 1st place for all categories will be given first choice and the rest will be given out by raffle! So your chances of getting a great prize is pretty good! We’ll be posting some of the prizes over the next couple of weeks on our Instagram (@grr_kw) and our FB, so stay tuned!
