T100 Marbella
A 100 km middle-distance race on Spain's sun-soaked Costa del Sol — big enough to feel epic, close enough to the sea to feel magical.
Where it is
Marbella, Spain
Is this your race?
The T100 format is a genuine 100 km challenge that demands real preparation — this is not a race to enter as your very first triathlon. The Marbella edition adds a hilly mountain bike leg and an open-sea swim where wetsuit use is decided on race morning, which raises the bar further. That said, if you have a season or two of shorter races under your belt and you love the idea of finishing on a Spanish beach with a festival waiting for you, this is a spectacular goal race to build toward. Beginner fit 2/5: T100 baseline 2, −1 hilly bike into the mountains; the open-sea swim with uncertain wetsuit rules is neutral rather than a positive, so no further adjustments apply.
✅ You’ll love it if…
- You have already completed at least one Olympic-distance triathlon and want a bigger challenge
- You thrive in warm Mediterranean weather and love open-water swimming
- A festival-style finish line with a crowd atmosphere motivates you
- You enjoy climbing on the bike and want a course that rewards training effort
⏳ Build up first if…
- You have never done an open-water swim race — get comfortable in the sea first at a shorter event
- Your longest bike ride is under 60 km — build up gradually over several months
- You are brand new to triathlon — start with a Sprint or Olympic race this season, then target Marbella
- You struggle in heat — practice training in warm conditions and nail your hydration strategy

The course, demystified
The race starts at sea level on Marbella's beaches, climbs into the mountains on the bike, then brings you back down to the coast for a run finish — a shape that rewards patience on the bike and saves something for the legs on the run.
Respira y flota (breathe and float) — the start is in the open Mediterranean Sea off Marbella's beaches. Typical water temperatures run 23–24 °C, which feels comfortable and refreshing. Wetsuit use is not guaranteed; the final call is made on race morning based on the measured water temperature, so pack your wetsuit but be ready to race without it. The sea setting means conditions can vary — think gentle ripples on a calm day, or some chop if the wind picks up.
The bike leg heads away from the coast and into the mountains surrounding Marbella. Expect a hilly 80 km with sustained climbing — the exact elevation gain is not published, but the course is officially described as hilly with mountain roads. This is the leg that will define your race. Ride conservatively on the climbs, eat and drink on schedule, and remember you still have 18 km of running ahead of you.
The run is described as lightly undulating and returns to sea level — a welcome relief after the mountain bike leg. You will be running back toward the coast and the finish-line festival, which is a powerful motivator when your legs are tired. The exact surface and route are not yet verified for 2027, so check the official race page closer to the event.
