Battle Cancer vs Terrain Race : distance, stations, prix et difficulté comparés (2026-27)

Battle Cancer is a fitness fundraising event series in which athletes raise money for cancer charities and compete in hybrid fitness challenges. Since 2019, the organisers say, more than 100,000 athletes have taken part in events across over 15 cities, including London, Glasgow, Dublin, Paris, Berlin, Barcelona, Dubai, Singapore and Miami.

The main Battle Cancer Challenge is a 90-minute event for teams of four (male, female or mixed). Teams rotate through nine stations in three zones, Endurance, Burn and Power, working five minutes of maximum reps followed by four minutes of rest at each. Hybrid 3|20 is a format for individuals or pairs: three minutes of work per station across nine stations, then a 20-minute maximum-distance run. Both formats have a Challenge division that allows movement modifications and a stricter Compete division. Money raised counts as points on the leaderboard, so it suits groups who want a sociable team event with a charity goal.

Terrain Race is an obstacle and mud 5K produced by EventLab, a US company that also runs fun-run brands such as Bubble Run, Muddy Dash and Blacklight Run. The current event is Terrain Race Irvine, held at Oak Canyon Park in the Silverado area of Orange County, California.

The course is about 3 miles (5 km) of rugged terrain with climbs, crawls, walls, ropes, monkey bars and mud pits. Participants pick a start time and run in waves with friends; a VIP package adds a priority wave start and extra merchandise. Packet pickup is offered the day before the race. The format is aimed at recreational runners, groups and first-time obstacle racers looking for a muddy, single-distance event rather than an elite competition.
