US fans, we hope you are free to watch these races on Thursday night (9:45 pm ET) as they are LOADED. In the women's race, Peres Jepchirchir returns to action for the first time since setting the 13.1 WR two years ago while the men's race features 5 young studs all 21 or younger plus Julien Wanders.

We know Selemon Barega ran 12:43 but in the end decided you can't really be World #1 if you failed to medal at World U20s and the African champs.

Kamworor cemented his status as the biggest young talent in the sport with by coming from 12 seconds down on the final lap to overcome a heroic effort by Uganda's Joshua Cheptegei.

Geoffrey Kamworor is looking to become the 1st man since 2006 to successfully defend his world cross country crown. Can he do it? If he falters, who is likely to win? Can the Americans possibly pick up their first individual medal since Alberto Salazar's silver in 1982? They've certainly got a good chance, particularly if Olympic 5000 silver medallist Paul Chelimo, who is in Uganda ready to race the 10k (but currently only on the 4 x 2k relay), ends up running.
