My son competed for 4 years and then had to leave gymnastics because of an achilles injury that wouldn't rehab sufficiently. That was a year ago and we're still looking for a new sport for him. He has been doing parkour and loves it (mainly for the flips), but there don't seem to be many opportunities for it where we're moving (or just generally). Seems like more of a fun hobby. Plus, it can irritate his achilles sometimes as well, for the same reason gymnastics did. He is generally very athletic and is good at almost everthing he tries, but he doesn't want to play organized team ball sports. He was on a swim team a few years ago, and is a strong swimmer, but he doesn't like swimming competitively (he gets bored by the fact that there are no new skills to learn, like in gymnastics, you just swim swim swim and try to get faster). I've been thinking maybe rock climbing? Any other ideas?
