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)
20% of all entry fees are given directly to charity – The Triathlon Trust – who engage school children in the UK to become more active through the particiaption of triathlon.
