How does someone who spent several years trying to master the 10k and was an also ran, go on to be amonst the greats in the half and marathon. SHe's equal to Goucher, Flanagan, Huddle and the like. All who ran sub 15 for 5k, 30 minutes and change for 10k.
Hasay barely qualified for the trials int he 5k. She barely ran sub 32 for 10k on the track last year.
And now she's running half marathons at her 10k (on the track) pace? A 2:23 at Boston with the only US women who raced faster on Boston being an Olympic champ, an olympic medalist, and last years 6th place finisher in the Olympics.
It defies logic.
