About ultramarathons

An ultramarathon is any race longer than a marathon. In the UK that ranges from friendly 50K trail runs to brutal 100 milers, mountain rounds, multi-day stage races and winter epics. This page lists UK ultras by date, with distance, terrain and a direct link to enter.

Read the full guide

What counts as an ultra?
Anything longer than the 26.2 mile marathon distance. The most common UK distances are 50K, 50 miles, 100K and 100 miles.
What's a good first ultra?
A well-supported 50K on trail with generous cut-offs. Look for events with regular checkpoints and a waymarked or familiar route, such as a national trail.
Do I need qualifying races?
Some of the tougher events need previous finishes or ITRA points. Check the entry requirements on the organiser's site before you enter.
What kit will I need?
Most UK ultras have a mandatory kit list — typically a waterproof jacket with taped seams, phone, foil blanket, whistle, head torch and food. Each event page links to the organiser for the exact list.
