The aim of the present study was to examine the performance of the world’s best runners in 10km, half-marathon, marathon and 100km by age, sex and nationality during 1999-2015 using data from International Association of Athletics Federations (IAAF). A total of 38,895 runners (17,136 women and 21,759 men) were considered with 2,594 (1,360 women and 1,234 male) in 10km, 11,595 (5,225 women and 6,370 male) in half-marathon, 23,973 (10,208 women and 13,765 male) in marathon and 733 (343 women and 390 male) in 100km. Most of the runners in 10km (women 40%, men 67%) and half-marathon (women 30%, men 57%) were Kenyans. In marathon, most female and male runners were Ethiopians (women 17%, men 14%) and Kenyans (women 15%, men 43%), respectively. In 100km, most runners were Japanese (20% in women and men). Women were older than men in 10km (32.0±6.0 versus 25.3±4.3 years, p<0.001), half-marathon (27.5±4.7 versus 25.9±4.1 years, p<0.001) and marathon (29.5±5.5 versus 29.1±4.3 years, p<0.001), but not in 100km (36.6±6.1 versus 35.9±5.5 years, p=0.097). Men were faster than women in 10km (28:04±0:17 versus 32:08±0.31 min:sec, p<0.001), half-marathon (1:01:58±0:00:52 versus 1:11:21±0:01:18 h:min:sec, p<0.001), marathon (2:13:42±0:03:01 versus 2:35:04±0:05:21 h:min:s, p<0.001), and 100km (6:48:01±0:11:29 versus 7:53:51±0:16:37 h:min:sec, p<0.001). East-Africans were not the fastest compared to athletes originating from other countries where only Ethiopian men were faster than all other men in marathon. In summary, (i) most runners were from Kenya and Ethiopia in 10km, half-marathon and marathon, but from Japan and Russia in 100km, (ii) women were older than men in all distances except 100km, (iii) men were the fastest in all distances, and (iii) Ethiopian men were faster than all other men in marathon.
