Delta (200m) – The length a track of this radius is longer than the inside track for a 200m race (and thus how much lead-in is needed to make it a fair race) Delta (400m) – The length a track of this radius is longer than the inside track for a 400m race (and thus how much lead-in is needed to make it a fair race)
