Well it appears that there may nutrition on courses this year. An article on slowtwitch.com, that they WTC has partnered with Powerbar for a new drink called Perform. The product will available in June. The races that it will be served on the course are 70.3 Rhode Island, 70.3 Racine, 70.3 Miami, Ironman Louisville, Ironman Wisconsin, Ironman Florida, Ironman Arizona, Ironman Lake Placid. It will also be at the 70.3 Championship in Clearwater and Kona.
If I have been training based on the Gatorade that is usually on the course, I wouldn't be to happy right now. I know a couple of these events are coming up very shortly and will catch some people off guard.
Just recently Gatorade, changed our it marketed it's endurance formula, it is now more expensive, but doesn't have any changes in nutritional value. Always be on the lookout for changes.
