For most athletes, a sprint triathlon is relatively short in duration. We estimate the bulk of the race field will finish anywhere between 60 and 90 minutes for most sprint triathlons.
There is no need to eat like you're taking on an Iron Distance Event. In terms of food and drink before and during the race, the bare minimum will be fine for most people. As we know though, all athletes are different. While there is no single wonder recipe that will work for all and sundry, there are some general rules of thumb to help guide you to through the nutrition part of a sprint distance tri, especially if you are new to the sport.
So to summarise – a light breakfast a couple of hours before the race, one energy bar as a pre-race snack, 1 x 750ml isotonic drink and 2 gels for the bike.
Keeping it simple and easy. Some athletes might prefer a different method of feeding their bodies which is totally understandable. We are such diverse specimens that a method which might work for one, might not work for the other.
The recipe above is however a good yardstick for the newbie/novice triathlete still getting into the sport and who has still to learn what works for them.
Good luck!
