Looking for a challenge? Climb a vertical mile (5,280ft) in a semester! This is a great way challenge yourself in a fun way that also encourages you and your friends to climb regularly. Keep climbing, and let the OP staff member on duty know how many different routes you climbed to the top of the wal after each session. Once you've climbed 145 routes to the top of the wall, you've done it! The first ten people to complete the challenge will recieve a t-shirt and to show that they are a part of the Mile High Club!
