The world's major hiking and mountain events — the ultra-trail races, trekking festivals and mountain gatherings that define the global trail community. Each entry links to the official organizer. For race distances and entry details, see the Trail Race Calendar.
The events on this page are the gatherings that define the global trail and mountain community — the races that draw the world's best ultra-runners, the festivals that celebrate mountain culture, and the multi-stage expeditions that test multi-day endurance. They range from a single-day trail marathon to a week-long self-sufficient desert race, but they share a common thread: they bring people together in the mountains for a shared, challenging experience.
Unlike independent trekking, these events provide a structured framework — marked courses, aid stations, timing, medical support and a community of fellow participants. For many, that structure is the appeal: a goal to train for, a day (or week) to test yourself, and a shared experience with hundreds or thousands of like-minded people.
Single-stage ultra-trails (UTMB, Western States, Transvulcania, Mont Blanc Marathon) are one-day races from 50 km to 100+ miles, with aid stations and cut-off times. They are the most common format and the entry point for most ultra-runners.
Multi-stage races (Marathon des Sables, Dragon's Back Race) unfold over consecutive days, each day a self-contained stage. They test multi-day endurance, recovery and self-management — and in the case of Marathon des Sables, self-sufficiency (you carry all your food and gear). Extreme-distance single-stage races (Tor des Géants at ~330 km) are a third category — a single push lasting days, with minimal mandatory rest.
Beyond racing, mountain events include trekking festivals, alpine club gatherings and mountain film festivals (such as the Banff Mountain Film Festival, which tours globally). These celebrate mountain culture without competition and are open to everyone, not just athletes.
Racing is the obvious way to participate, but it is not the only one. Volunteering at an aid station, finish line or registration desk is how many people first experience a major event — it is free, you see the race from the inside, and you contribute to the community. Most races recruit volunteers months ahead through their official website.
Spectating is another way in. UTMB week in Chamonix, Marathon des Sables in the Sahara, and the Mont Blanc Marathon festival are major mountain festivals with a public atmosphere — you can watch the starts and finishes, attend the expo, and soak up the culture without entering. For a first taste of the ultra-trail world, spectating a race like UTMB is the best introduction.

These events are more than a single race — they are week-long mountain festivals with multiple distances, an expo, public events and a race village. They are the best events to attend as a spectator or first-time participant, with distances for every level.
These events test multi-day endurance and self-sufficiency — Marathon des Sables in the Sahara (self-sufficient) and the Dragon's Back Race along the spine of Wales (self-supported between checkpoints). They are among the hardest mountain events in the world.
The legendary one-day ultras — Western States 100, Hardrock 100 and Tor des Géants. Each is a benchmark of the sport, with qualification and lottery entry. They are as much mountain expeditions as races.
The calendar follows the northern-hemisphere mountain summer. April: Marathon des Sables (Moroccan Sahara). May: Transvulcania (La Palma). Late June: Western States 100 (California), Mont Blanc Marathon (Chamonix). July: Hardrock 100 (Colorado). Late August: UTMB Mont-Blanc (Chamonix). September: Tor des Géants (Aosta Valley), Dragon's Back Race (Wales).
If you want to attend as a spectator or volunteer, book accommodation early — Chamonix during UTMB and Mont Blanc Marathon weeks is fully booked months ahead. If you want to race, work back from the event date to plan qualification and training. Always confirm dates on the official event website — we display the established recurring pattern and flag honestly when the next edition date has not been officially announced.
For racers: confirm the qualification and entry requirements on the official website well ahead. Lottery races (UTMB, Western States, Hardrock) require planning a year or more in advance — complete qualifying races, enter the lottery, then plan travel only if selected. Direct-entry races (Marathon des Sables, Transvulcania, Mont Blanc Marathon) sell out fast — register on the day entries open.
For spectators and volunteers: book accommodation as soon as the event dates are confirmed — mountain towns fill up months ahead for major events. Volunteer registration usually opens 3–6 months before the event through the official website. For all participants, carry mountain insurance that covers rescue in the event country — even spectators on mountain trails need it.
