Joshua Cheptegei is my pick on the men's side. 5k and 10k world record holder. Olympic 5k champ. World 10k champ. Defending champ.
If he adds this one to the list of accomplishment, he'll be entering all-time great territory.
Jacob Kiplimo world record holder and half and runner-up last time is biggest thread. But Selemon Barega- Olympic 10k champ, Geoffery Kamworor, others are possibilities.
*Women's side this is Letsenbet Gidey's race to lose.
Any other thoughts?
