50K ultra runs

A 50K ultra is the most popular way to step beyond the marathon. Events combine endurance, adventure and achievable distances, making them ideal for first-time ultra runners. Use the filters to find 50K ultras by date, location or terrain.

A 50K ultra run covers just over 31 miles, offering a manageable introduction to ultra-distance running without the commitment of longer events. Many 50K ultras take place on scenic trails, rolling countryside or multi-loop courses, making pacing and nutrition easier to manage.

These events are popular with marathon runners looking for a new challenge, as well as trail runners keen to explore longer distances. You’ll find beginner-friendly options with generous cut-off times alongside more technical courses for experienced off-road runners.

Use the filters to narrow your search by date, location or route type — to find your perfect ultra.

If you’re aiming to go further, you can also explore our 100K ultras or 100-mile ultra events once you’ve built confidence at this distance.
