Races and results
Kejelcha withdraws from Valencia Marathon with injury
Yomif Kejelcha is out of the December 6 Valencia Marathon with an injury, organizers announced. He ran 1:59:41 behind Sabastian Sawe (1:59:30) at April's London Marathon, where the two became the first men under two hours in a record-eligible race, CITIUS MAG says. Boston champion John Korir still headlines the men's field.
The second-fastest marathoner in history will miss the year’s last big shot at another sub-two-hour marathon.

Holmer: heat training does not fix your ability to burn gels
Brady Holmer says heat acclimation drops heart rate and core temperature and raises plasma volume, but does not restore your ability to burn the carbohydrate you swallow. Tim Noakes argued the cause was lower blood glucose in the heat and guessed gut absorption was reduced.
The rate of intestinal glucose absorption may be reduced during exercise in the heat; that's my guess.
Fitzgerald says VO2 max workouts only raise it in the short term
Jason Fitzgerald says all the advice about workouts to raise your VO2 max (the ceiling on how much oxygen you can use) is missing the words "in the short term." For the long term, he says, you would skip those sessions and build the aerobic engine with easy and steady running over years.
Of course, you still have to do some VO2 work! But playing with fire has risks...
