Thames Path Challenge

The riverside 100 km: the full route follows the Thames towpath upstream from Fulham to Henley-on-Thames, with the next edition starting on Saturday, September 11, 2027. The towpath keeps the climbing modest, about 350 meters in all, which makes this a natural first 100 km, but hours of the same flat stride wear on hips and feet, so long flat training walks matter as much as hills. The route is marked with glow sticks for walking through the night. Shorter stages include a 72 km three-quarter route, 50 km halves and quarters of about 22 to 28 km, plus a two-day daylight 100 km and a 100 mile version with a 48-hour cut-off. The Ultra March medal needs the 100 km walked in under 24 hours. The picture shows finisher medals from 2017.
