I am a 35 year old, 6'5 245 lbs. male who wants to start training for triathlons. I am primarily thinking about the sprint distance. I used to run and swim a lot, but now my main cardio has been cycling. I am an avid weight lifter and plan on cutting back to two full-body weight room days a week in addition to my tri training. I actually shed body fat easily, and plan on getting down to the 225 range. I have told some people this and they have said that even at 225 I am far too heavy for this sport.
