Inflatable 5K Cheltenham 2026

The Inflatable 5K Cheltenham is a fun run featuring inflatable obstacles, held at Cheltenham Racecourse in Gloucestershire, using the GL50 4SH site. Instead of a typical road race, the course involves navigating giant inflatable obstacles. Participants will jump, slide, bounce, swing, and crawl through tunnels. While named the 5K, participants can select 2.5k, 5k, 10k, or 15k distances. Start waves operate from morning until early afternoon. The course is designed for those seeking a playful challenge rather than a competitive time trial. It welcomes beginners, families, groups of friends, and experienced runners. UK Running Events promotes this series as a large-scale inflatable obstacle course, and the Cheltenham event adheres to that high-energy style. It also serves as a charity event: Team NHS Glos participants can fundraise for local hospitals, receiving a charity running top, fundraising guidance, and support from the charity team linked to their fundraising goal.
