100 kilometers in 24 hours 2026

The start and finish take place in Colmenar Viejo, near Madrid 🇪🇸. The concept? A true personal challenge! It is not a competitive race, the objective is "simple": cover the mythical distance of 100 km on foot, within a maximum time of 24 hours 😲.

You manage your pace! 🎒 You decide how you want to tackle this challenge:

• Alone or in a group.
• Walking at a brisk pace with real breaks, or moving continuously with mini-stops.

You won't be left alone in the nature! The route includes no less than 19 supply points and 3 large rest areas (in sports complexes) for eating and recovering a bit. It's the perfect event if you're looking to push your limits and experience an unforgettable human and sports adventure.
