I agree...outside the IM and 70.3 World the numbers seemed to have peaked at out local triathlons in 2009 and are in decline....I am in Minneapolis which has an incredible offering of Triathlons in the local marked, and its still healthy, but the BOP participants seemed to have moved on to the Mud Run/Zombie Run/Color Run experience. At the end of the season I am going to run some numbers but I was at a triathlon that had 400-500 people in 2009 and had about 270 this year....

3 years ago I was seeing MANY Mt bikes in the tranisition area in local sprint triathlons but there is noticably less of the participants this year....
