Hello - I am 48 and thinking of attempting a sprint triathlon. I'm 5'8", 183 lbs. I am an avid cyclist (I ride 50+ miles per week most of the year) and I run 8-10 miles per week, usually 3 mile runs at lunch and the occasional longer weekend run. Not being a regular swimmer has kept me from triathlons, but I am now thinking of trying.
Hey Steve! I'm a re-newbie to Triathlons, getting back into it after a 4-year hiatus. Welcome to the forums and welcome to the sport! Good luck with your endeavors!
Something you might do is be sure to log your workouts so we can see your progress and cheer you on. It also helps you see how your own training is going.
