I didn't get the chance to watch the race. Looking at the splits, Meb was matching things perfectly for the first 35k. He just cratered and lost 2:19 on the lead over the next 5k before losing another 1:06 in the final 2k. Such a sudden drop in pace seems like it would be more fueling than anything as people usually implode more gradually. Anyone know what happened? Just a horrible bonk?
