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.

Mo Farah's 2017 campaign begins on Saturday morning in Scotland where he'll try to prevent Garret Heath from pulling a stunner in Edinburgh for the fourth year in a row. Euro XC champ Aras Kaya of Turkey, plus Club XC champ Sam Chelanga and U.S. Olympians Leonard Korir and Hillary Bor also feature in the men's 8k. In the women's race, Euro XC champ Yasemin Can of Turkey faces U.S. Olympian Marielle Hall and Sarah Pagano. Laura Muir, Kyle Merber and Will Leer are among the legs in the mixed-gender 4x1k relay. Watch it live starting at 8:15 am ET. *MB: Garrett Heath goes for #4 vs Mo Farah: 2017 Great Edinburgh XC preview
