Sunday evening : 10pm and race time. Greenwich foot tunnel and 4 goodgymers ran 10km in the tunnel. Starting every 5secs, 86 runners set off to run 27 laps of the tunnel. Crazy race with some zigzags as open to the public. Very hot and stuffy but a fun and crazy 10km. Goodgym Haringey and Goodgym Ealing Steph Ducat
