The background shows a tree-lined street with spectators and buildings. Three men are running in a marathon, all wearing numbered bibs. The man on the right is wearing a t-shirt with the text “ri web.” The background consists of trees and a stone fence. They appear focused and determined as they run. A large group of runners on a street participate in a race near a historic stone building. Spectators watch from the sidewalk. A police officer monitors the event near a traffic light. The scene includes various cars and buildings lining the street.

This was a very enjoyable experience. I took part in the 10k. The parking was easy. The event village quite small and intimate, which I liked. The race itself was picturesque and mostly pleasurable (apart from Heartbreak Hill). I'll do it again next year.

I got a pb on this course! Scenic route with one long, tricky hill (mile 8). Plenty of volunteers along the way. It's well organised with ample parking. It could do with pacers on the run too.

Picturesque and challenging route through the Oxfordshire hills (Heartbreak hill) around Henley. Was bathed in sunshine this year and a lovely family day out. Will do again next year.
