Mean (SD), [range], 22 subjects (58% of the sample) was classified as Local Class, 15 subjects (40% of the sample) was classified as Regional Class, one subject (3% of the sample) was classified as National Class. Baseline 5-km time trial performance was taken as the best result between two baseline 5-km time trials held one week apart. Baseline fasting blood glucose values was the average fasting blood glucose values for both baseline sessions held one week apart. All variables were normally distributed (Shapiro-Wilk test p > 0.05 for all).
