I've always been intrigued by the prospect of who makes the the best 800m runners. It seems like guys who top out at the 800m generally do better. So I went for the middle between arguably the best 400m and 1500m runners on earth. If you gave Kirani James and Absel Kiprop one year to train specifically for the 800m who would you pick to win? Kiprop has run 1:43 before as a P.R while James has no official 800m PR but as run 43 for the 400m. Who would you take?
