Taking on an ultra is a powerful step into the world of endurance running. Events push beyond the marathon distance and test stamina, pacing and grit across a huge variety of routes. You’ll find everything from rolling countryside trails and coastal paths to brutal mountain courses that reward every mile with unforgettable views.
Many ultras offer route choices, time-based challenges or multi-loop formats, making it easy to find something that matches your goals. If you're exploring your first ultra, shorter-distance events are an ideal introduction, while experienced runners can take on bigger point-to-point challenges, technical terrain or long-hours formats.
Looking for a specific distance? Explore our dedicated hubs for 50K ultras, 100K ultras and 100-mile events to discover races suited to your experience level and training goals.
Use the filters to narrow your search by date, location or route type — and find your next all-day (or all-night) adventure.

Ultra marathon FAQs
Answers to the most common questions about running an ultra marathon.
Any running event longer than the marathon distance of 26.2 miles is classed as an ultra. Formats range from trail ultras and looped courses to long point-to-point challenges.
Some ultras welcome first-timers, especially shorter-distance or looped formats. Others require experience due to technical terrain or long cut-off times. Always check the event details before entering.
Many ultras take place on trails or mixed terrain, but some are run on roads or cycle paths. Use the filters to choose the surface and route style you prefer.
Training time varies with distance and terrain, but most runners spend 12–20 weeks preparing for a shorter ultra and longer for more demanding events.
Ultras often require items such as hydration packs, waterproof layers, head torches and nutrition supplies. Check the mandatory kit list for each event.
Consider distance, elevation, terrain and cut-off times. If you're new to ultras, look at looped courses or shorter-distance events, or explore our 50K ultras hub for beginner-friendly options.
