River Thames Half Marathon

About this event

The River Thames Half Marathon follows a flat, fast course along the Thames towpath and quiet Surrey roads, starting and finishing near the historic Walton Bridge. The largely traffic-free route passes Hampton Court Bridge and winds through the gentle scenery of the Thames Valley. Now in its seventh year, the race has built a reputation for friendly marshals and solid organization. Pacers support runners targeting specific times, while chip timing ensures accurate results on this certified course. The late October timing makes it ideal for chasing a personal best or fine-tuning fitness ahead of an autumn marathon. Finishers receive a tech tee, medal, and goody bag.
