Finally got a chance to bike to my temporary work site (for training)...I was a little worried because it's over 2x as long my normal commute and basically all uphill for the entire 23 miles...only about 650 feet total of climb, but I had a heavy backpack, so that gives me an excuse to complain. But I made it in the exact amount of time I hoped and I didn't fall asleep during class. Ride home was pretty hot and my gear wasn't dry from the morning (ewww), but since it was downhill coming back, it made for a reasonably pleasant and easy ride, which ended up being slightly longer, so round trip was right about 50 miles...not sure how many times a week I'll be able to sustain that, but it's a nice alternative to spending $4 in tolls and $7 in gas every day.
