The wind can zap you, that's for sure. I agree with everyone else, tho- could have been a combination of lots of factors (not eating/drinking enough/jumping to twice the distance/wind/duration in the saddle).

Try to think about what you ate before and during the ride. Was it enough? How much did you drink? What kind of nutrition were you taking in during the ride (most people can only tolerate 200-300 calories an hour with both liquid and solid foods).

The wind is terrible. Living in Oklahoma, the wind does NOTHING but blow. There are very few trees to block it. I have a love/hate (more of a hate/hate, but whatever ) relationship with the wind. I tolerate it. I will change routes depending on how the wind is blowing (going east/west if it's a strong north or south wind, or going north/south if it's a east/west wind).
