these are the rough dimensions of a regulation WFTDA/MRDA roller derby flat track. (Calculated from the Official Track Design ) The length of a WFTDA track is (17.5 * 2) + (12.5 * 2) + (14 * 2) = 88 feet. At any one point, a WFTDA track is no wider than (12.5 * 2) + 15 + 13 = 53 feet.
Long-Distance. The 5,000 m and 10,000 m are the long-distance races run on a track. The shoes worn by long-distance runners still have spikes, but are a little heavier and more solid than shoes designed for shorter distances.
