You've already done a triathlon, but have you ever done THE T24?

24 hours, an idyllic location, three disciplines to combine until you drop (or almost). Swimming, cycling, running, all with the breathtaking landscapes of Brittany as a backdrop. Solo or relay, the goal is clear: to surpass yourself and leave with memories that will last a lifetime.

 

What you'll find there:

A magical setting and super-welcoming Carantécois.

• A unique format: 4 hours of swimming, 12 hours of cycling, 8 hours of running. A challenge to experience solo or in relays (2, 4 or 6 participants).

• A very simple rule: each team member must do at least one loop of each discipline. Afterwards, it's unlimited relays!

• A crazy atmosphere: between the Australian-style outings, the bike relays until the end of the night, the beach, the crazy encouragement and the moments of doubt at 4 a.m.... you'll make unforgettable memories.

• A dream base camp: meals, chill-out area, showers, music... (And if you manage to catch a nap, you're truly a champion!)

 

Course focus:

4 hours of swimming (from 9 a.m. to 1 p.m.):

You do 1,000 m loops. Each lap? Wild crowd, you're a star every time you get out and into the water!

🐟 1 km = 15 points. A fish in the water and points, what could be better?

 

12 hours of cycling (from 1 p.m. to 1 a.m. - sunset at 10:21 p.m.):

A 24 km loop, to do in ultra mode or in strategic relays. Night falls, legs turn, and strategy can change everything. (Don't forget your lights!)

🚴 1 km = 1 point. The points will quickly add up.

 

8-hour running race:

Last stage, saving the best for last! Access to Callot Island is subject to tide times and weather conditions. Here's what it looks like:

From 1 to 2 hours: Route without Callot Island - 3.75 km - 15 pts

From 2 to 6 hours: Route with Callot Island - 6.75 km - 27 pts

From 6 to 9 hours: Course without Callot Island - 3.75 km - 15 pts

 

5 (very) good reasons to participate:

• Wild beaches, coastal landscapes... you'll be amazed, that's for sure.

• Forget monotonous courses! Here, you have a bit of elevation, challenges, and a natural setting that will test you.

• An event that has been designed to give you an unforgettable experience. The T24 Breizh is brand new, fresh... and it promises to be great!

• You'll find yourself in the heart of nature, living in the moment and pushing your limits. A true return to basics.

• A little (a lot) of effort, and a good Breton beer to celebrate your performance. Because after 24 hours of sport, it's worth it!
