Practical advice before registering for your first triathlon
Physical preparation
Plan at least 8 to 10 weeks of progressive training with strengthening, sequences and a weekly long run.
Test your equipment beforehand
Don’t discover your trifunction or your bike on the big day. Choosing the right wetsuit is essential. Anticipate transitions, outfit changes and minor technical adjustments.
Getting to know the rules
Drafting, bibs, transition zones and penalties: a little reading goes a long way.
Locate the route if possible
Visiting the site a few days before the race allows you to visualize the start area, transitions and loops, and to reassure yourself.
Nutrition and triathlon: what you need to know
A key element of your success is good nutrition before, during and after your triathlon.. Before the race, it’s essential to optimize energy reserves with complex carbohydrates, while ensuring regular hydration. During the race, easy-to-digest foods such as gels, energy drinks and compotes help you keep up the effort. Last but not least, post-triathlon recovery is an important phase. The body will need specific care to avoid injury.
