What counts as an ultra marathon?

Any running race longer than the standard marathon distance of 42.195 km (26.2 miles). Common ultra distances are 50K, 50 miles, 100K and 100 miles.

What's the shortest ultra marathon distance?

50 kilometres (31 miles) is the traditional entry-level ultra and a good first step from the marathon distance. Many UK 50Ks run on trail or canal-side routes.

How long does it take to train for a 50K ultra?

Most runners need 16 to 24 weeks if they already have marathon experience. Training focuses on time on feet rather than mileage, with long runs of 4 to 6 hours.

Do UK ultras require mandatory kit?

Yes — most ultras require waterproof jacket, hat, gloves, food, water, whistle and map. Mountain and longer events often add survival bag, head torch and spare layers. Always check the race-specific kit list.
