Summer Marathon & Half Marathon — Phoenix Running

The Summer Marathon & Half Marathon — organised by Phoenix Running — is a flat, lap-based event held on the River Thames towpath at Walton-on-Thames. Runners complete four laps for the half marathon or eight laps for the marathon along a riverside towpath route that the organiser describes as flat and fast. The course is presented as accurately measured and UKA certified, and the event page emphasises a low-key, scenic atmosphere suitable for steady running or targeting a personal best.

The event fields are limited and entries are managed online via the organiser's registration link, with a single official start time listed at 08:30 on race day. All finishers receive a medal or memento, and the listing highlights straightforward logistics with a start area on Waterside Drive near The Weir Pub/Xcel sports hub. Phoenix Running positions the race within its wider calendar and notes rules and age restrictions in line with UK Athletics guidance.
