I have been involved with triathlons for a couple of years now but have stuck to sprints and olympics up until now. My sprint time averages 1:05 throught the season and my PR is 59min. I am looking to drop down to 55 minutes for sprints and will be doing a 1/2 Iron and full iron at the end of the season, the REV3 wisconsin followed by the REV3 Cedar Point. My only concern is my diet, or lack there of to be more accurate. I dont drink any caffiene but dont watch what I eat at all. Where should I start as far as daily nutrition goes to reach my goal? Thank you for your assistance.
