Where the numbers come from

TrackMark uses the standard 400 m track layout: 84.39 m straights, a 36.5 m inside radius, and the official hurdle and relay-zone spacing. Hurdle marks sit at 13 m then every 8.5 m (100 m hurdles), 13.72 m then every 9.14 m (110 m), and 45 m then every 35 m (300 m and 400 m). Relay zones begin 20 m before and end 10 m after each 100 m handoff point.

Start lines, 300 m and 400 m hurdle marks and relay triangles are staggered lane by lane, so another lane's mark gives your lane a different distance. TrackMark works that out by going straight across the track from the mark. It depends on lane width, so set yours under My track's paint.

A shoe length is taken as 0.3 m and a big step as 1 m. It has not measured your track. Paint colors and which marks exist vary, so check a mark with a tape or wheel the first time you rely on it.
