Henley River Half Marathon, 10K & Junior Race April 2026

The Henley River Half Marathon, 10K & Junior Race April 2026 is a one-day running event set on the banks of the River Thames, with start and finish at Temple Island Meadows in Henley-on-Thames. The race day offers a Half Marathon, a 10K and a Junior Race, and is organised by RunThrough. The course is described as mixed terrain and undulating, weaving along riverside paths and parkland to provide scenic views and varied footing. Runners of differing abilities are catered for, from competitive half marathoners to families and younger participants in the junior event.

Race logistics include staggered start times (Half Marathon 09:00, 10K 09:30 and Juniors 11:30) and a lap structure with the Half Marathon run as a mini lap plus two laps while the 10K is a single lap and juniors use an out-and-back. Entries include chip-timed results, a unique themed medal and free race photos, with water stations roughly every 5 km and a secure on-the-day baggage area. The event provides spectator information and course marshals for safety and wayfinding, and additional event pages give route maps and athlete guidance. Participants are advised to consult the official event pages for full event day logistics and any updates nearer the date.
