Beckenham Place Park, Beckenham Hill Rd, Beckenham, London BR3 1SY, United Kingdom
London - Beckenham Place Park Pretty Muddy 5k 2026 is a charity obstacle 5k run/walk organised by Cancer Research UK as part of the Race for Life series. The event combines climbing, crawling and sliding around a purpose-built obstacle course set within Beckenham Place Park and is designed to be accessible to walkers and runners alike. Participants are encouraged to fundraise for life-saving cancer research, with a minimum fundraising target set for entrants. The atmosphere is family-friendly and aimed at fun rather than elite competition.
Start times are staggered in 15-minute waves from around 12:30 and participants may choose their preferred wave on registration, with group entry options available. The course is mixed grass and paths with undulating sections and some steep inclines, and the event notes it is not suitable for wheelchair users or pushchairs. On-site facilities include refreshments, toilets and a secure bag drop, and the event encourages spectators and post-race picnics in the park. Entrants receive fundraising support from Cancer Research UK and practical information such as the What3words start location and travel advice to help plan arrival.
