9.6 miles. I am a bit out of shape and that was tougher than it should have been. My Gatorade really slushed towards the end. 11F on the thermometer. Downhills at 30 mph got a little cold.
Things for next time: ankle and wrist warmers. Better gloves, my $9 work gloves from Home Depot are too ventilated on the backs. My top was a little overheated and sweat made me chilly when I stopped to munch my frozen Gatorade (hard to drink through a balaclava!)
My cheap-o balaclava, the Giordini Lavawool from Campmor.com, works awesome. Above 10 mph my sports wrap sunglasses were fog-free. If anyone has any good cold-weather tips (aside from the ubiquitous "htfu"), let's hear 'em!
Now my hands are aching as they warm up. Time for some miso soup and a turkey chimichanga.
