Underground Ultramarathon

We’ve created a brand new challenge – choose one from the following London Underground lines, based on the distance that suits you most or maybe the line you take most often. Better still, why not get a group of friends together and take a line each as a race or team effort.

Central (46mi/74km)

District (40mi/64km)

Metropolitan (42mi/67km)

Northern (36mi/58km)

Piccadilly (45mi/71km)
