Looking for UK 20 mile races? This page lists upcoming 20 mile running events across the UK, including race dates, locations, surfaces, entry status and official entry links.
Twenty mile races are especially useful for marathon training. Many runners use them as a final long race before a spring or autumn marathon to practise pacing, fuelling, kit choice and race-day routine.
Most UK 20 mile races are road events, but some use mixed-surface or trail routes. If you are using a 20 mile race as marathon preparation, check the course surface, elevation, timing and how it fits with your target marathon.
Entry availability varies by event. Some popular 20 mile races sell out quickly because they sit at key points in marathon training blocks. RaceScan helps you compare upcoming races and see which events are currently open.

FAQs about UK 20 mile races
Why run a 20 mile race?
A 20 mile race is useful for marathon preparation because it lets you practise pacing, fuelling, kit choice and race-day routine without covering the full marathon distance.

Many UK 20 mile races take place before major spring and autumn marathons, often during peak marathon training periods.
Are 20 mile races good marathon training?
Yes. Many runners use 20 mile races as marathon training because they provide a controlled long-distance effort and a useful test of race pace, nutrition and confidence.
Are UK 20 mile races usually road or trail?
Many UK 20 mile races are road events, but some use mixed or trail routes. Check the surface and elevation before entering, especially if you are using the race as marathon preparation.
Do 20 mile races sell out?
