My wife and I got into it a couple years ago. We've done 2 Ironmans (Boulder and Louisville), 2 halfs (Boulder 70.3, Michigan Titanium Half Iron) and a bunch Olympic and sprints. We enjoy it, this year no Ironmans though. Mywife and I have lived in COlorado for 2 summers and both were spent training. I'm in the process of building a new high end mountain bike so this year I'm gonna ride the wheels off that thing. I'll still do some sprints and olympics but nothing long that I need to specifically need to train for. I am looking forward to doing some more Xterra off road tris this year though.
