There was also some extravagant running in the heats of the boys' 3000m. Not content with merely qualifying for the final, the African favourites achieved some extraordinary times, especially considering Nairobi's high altitude.

Selemon Barega of Ethiopia took the first heat in 7:55.73 after running the final kilometer in just outside 2:34.

The performance took him to third on this year's U18 world list. Stanley Mburu Waithaka of Kenya was the runner-up in 7:59.54, with Oscar Chelimo of Uganda and Merom Goitom of Eritrea both in the 8:08 range.

The pace of the second heat was only slightly more sensible. Edward Zakayo of Kenya took it in 8:04.85, evidently intent on proving a point to his Ethiopian rival Milkesa Mengesha, who finished second in 8:05.87.

The final kilometer took just 2:31 for the winner, much faster than was necessary, considering the first non-automatic qualifier in that race finished some 45 seconds behind.

There were no such displays in round one of the girls' 800m, although the races featured some impressive running. The fastest of the qualifiers for the semifinals was the Kenyan Jackline Wambui, winner of heat three in 2:08.24, 1.5 seconds ahead of Hirut Meshesha of Ethiopia.

The event favourite, Kenya's Lydia Jeruto, took heat one in a relatively pedestrian 2:10.37, but looked strong, running the final 200 meters in about 31 seconds.

The second fastest among the entrants, Ethiopian Netsanet Desta strolled to what looked like an easy victory in heat two, but was subsequently disqualified for a lane violation, leaving Vimbayi Maisvoreva of Zimbabwe the winner in 2:11.09.
