The Unknown Race is one of the most original self-supported bikepacking challenges in Europe, turning traditional ultra-racing on its head by removing the fixed route entirely. Instead of following a GPX track, riders must navigate between checkpoints that are revealed progressively during the event, making strategy and decision-making the true heart of the challenge.
The 2026 edition takes place in Reus, Catalonia, Spain, with riders starting and finishing at the same location. The route is approximately 1,000 kilometres, but the exact distance and elevation gain remain unknown until the checkpoints are revealed. The first checkpoint is announced just one hour before the start, and each subsequent checkpoint is only disclosed when riders arrive at the previous one, forcing participants to constantly adapt their route and strategy.
The Unknown Race follows a strict self-supported philosophy. Riders are responsible for their own navigation, food, accommodation, and mechanical repairs, with no outside assistance, support vehicles, or public transport permitted. The event welcomes riders of all backgrounds and allows participation in solo, pair, or trio categories.
With its progressive checkpoint format, charitable mission, and emphasis on adventure over pure competition, The Unknown Race offers a truly unique ultra-cycling experience. It is a race where the greatest challenge is not just endurance, but embracing uncertainty and making the best decisions when the road ahead is literally unknown.
Based on this event's terrain, difficulty and riding style.
The Unknown Race covers 1000 km with 20000 m of climbing along the way — a steadily rolling profile from start to finish.
A Endurance Road Bike is the right tool for The Unknown Race. Set it up with 30-35mm Tubeless rubber and gear it low — a 46/30T-50/34T (2x) chainring and 10-36T cassette will keep you spinning on the steeper sections.
The Unknown Race carries an overall difficulty rating of Advanced. The terrain itself is mostly smooth, fast-rolling surfaces, the climbing is consistently demanding, with sustained climbing, and conditions tend to run mild and generally comfortable.
The Unknown Race runs on March 31, 2026, placing it firmly in the spring riding season, when weather can still be unpredictable, so a flexible kit is worth packing.
Surface-wise, expect road throughout The Unknown Race — 30-35mm Tubeless tires are a safe bet.
