"How she never notched faster marathon and half performances is beyond me....."
How? Perhaps because she spent all those years pursuing world cross country, indoor track, middle-distance road races and outdoor track performances. 8 straight appearances at world cross (1st, 1st, 1st, 2nd, 3rd, 4th, 4th, 6th plus 39 national titles at all those disciplines...she wasn't a marathoner until she tried very late in her career. She was a classic middle-distance woman. If there's anybody else, male or female, close to achieving more than 39 national titles, I'd like to know who it is.
