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.
