yesterday's commute was pretty tough. although the rain held up, we had heavy winds that wreaked havoc in some of the burbs. definitely riding into a 50kmh+ wind takes a lot of extra energy out of you. my normal commute, by the mid-way point i was actually getting tired. the tuck position helped a lot to reduce frontal area, but with a 25 pound backpack on, the tuck position put strain on the back and arms as well. so, it was tim hortons to get a short respite and a dose of java, and completed the morning commute a half hour later.
