But the 10K is only raced once on the Golden League, in Brussels. Jos Hermens got them to do it at Hengelo too since the emergence of Gebrselassie, but that's just 2x season. The 5K is raced more so, but competition does not necessarily mean the athlete will go faster. Gebrselassie ran faster without any competition, and he probably could have gone better because he had to run his last mile in 3:59 when the pacemakers screwed it up for him.

It's ironic how the 5k/10k, perhaps the most raced of distances, remain the weakest.
With Kipchoge, Bekele, Shaheen, Sihine, and El Guerrouj, the 5K could come down, but the 10K is an unbelievable record. It even humbled Bekele; he could "only" run 58 for the last lap, and that's a guy who finished off a 27:05 at the Olympics in 53.02.
