Deadly Dozen is the original global fitness race: twelve 400-metre runs around an athletics track, each followed by a functional exercise station. Track races run all season, and the dates below come straight from the race diary.
THE OTHER FITNESS RACE
If the race you wanted is full, you do not have to wait for next year. Deadly Dozen mixes running with functional exercises against the clock, like other hybrid fitness races, but on a 400m athletics track: twelve laps, twelve exercise stations, and your result on the global leaderboard.
