The distances used were the "international" or "standard" ones, with a 1.5 km (0.93 mi) swim, 40 km (25 mi) cycle, and a 10 km (6.2 mi) run. The 2004 triathlon was identical to the first in distance, but the 100-athlete quota was evened between 50 women and 50 men. The quota was further increased to 55 women and 55 men for the 2008 Beijing Olympics and remained the same for London 2012.
