One word: headwind. Straight into a 15-20 mph headwind most of the way. Gusts higher. There are times (like this) when I wish my commute didn't go right along the river. There's NOTHING to break the wind. Oh well, better workout, I guess.
Knowing my luck, by the time I leave at 5, the wind will have shifted 180 degrees and I won't even get the benefit of a tailwind for my struggles this morning.
Still had fun, though!
Other random, thought... Some people look forward to the weekend so they can go bike riding. I didn't ride all weekend. But I was, in a very perverse way, looking forward to the week so I could get riding again!
