Henley River Half Marathon, 10k & Junior Race April 2027

The Henley River Half Marathon, 10K & Junior Race takes place in April in Henley-on-Thames, featuring mixed terrain routes along the Thames riverbanks. Adults can choose between a half marathon or a 10K race, with a separate junior race for younger participants. The half marathon begins in the morning, with the 10K starting 30 minutes afterward. The start and finish line are located at Remenham Farm, the same riverside location used for the Royal Henley Rowing Regatta. The course is characterized as fast yet undulating, offering a quick route that avoids being entirely flat. Its riverside setting, varied surfaces, and the inclusion of a family race option make it a suitable choice for club runners, those new to the sport, and families participating together on the same day.
