Here are the unofficial rules of chess track:
1) the board shall be placed on a table or whatever a couple meters before the start/finish line.
2) white lines up behind the start/finish line, and black lines up behind the 200m waterfall.
3) When the starter signals, white makes the first chess move and runs. Black can start running immediately.
4) each time a runner approaches the start/finish line, he/she must stop and make a legal chess move before crossing it, or be disqualified and go home devastated.
5) the match continues until one of the following happens:
a: one runner catches the other
b: one chess player wins the game
c: one runner is DQd by stepping off the track or failing to make a legal move between laps
d: both players agree to a draw or a draw is forced in the chess match, except
e: in the case of stalemate (no legal move) that player may not cross the start-finish line and must wait for the opponent to either catch them or DNF
