I meant to work at pushing the pace at 15-16 mph, and had to keep slowing down because of poor visibility. Today I felt stronger, too, which made it especially aggravating. I don't dare go so fast that I'm outrunning my headlight, especially as some of the same people who are out there without lights in clear weather are out there without lights when it's very foggy.
Fog is as bad as rain for getting tire rims wet, making braking less effective; another reason not to outrun my headlight. I'm glad I don't need glasses to see where I'm riding, because rain and fog get them, well, all fogged up. I'd need to get anti-fog spray for the lenses.
I hope for no fog tomorrow morning. I've had enough for a while.
