Two hours before the run and after an overnight fast, each subject consumed an isocaloric meal containing either low (GI = 37, LGI) or high (GI = 77, HGI) GI CHO foods that provided 1.5 g CHO(kg -1 body mass in random order. Each trial consisted of a 21km performance run on a level treadmill. The subjects were required to run at 70% VO 2max during the first 5km of the run. They then completed the remaining 16km as fast as possible.
