33 degrees. Made 4.35 miles in just over 14 minutes averaging 18.6mph overall, having hit only one light, just barely. Boarded the light rail, rode it into downtown (approximately 18 miles), parked in our building's key-access bike cage, and arrived in good spirits. Of course the ride home is never only 14 minutes. Between my home and the light rail station I lose 635 feet with only 13 feet of uphill along the entire route. So coming home I face a 635 foot elevation gain, and greatly reduced average speed. This is fine though; I arrive at work without having broken a sweat, and though I can't say as much for the ride home there's a change of clothes and warm shower at my destination.

I do typically turn my home ride into a slightly longer route; 6.5 miles. This avoids climbing a high-traffic hill. It's one thing to descend it at 35mph with cars going about 40. But the uphill lanes are narrower, traffic is still going 40, and I would be making seven or eight MPH along that segment with my pannier on the back. Much more fun to take a slight detour that takes me though roads with no traffic on them. The elevation gain is the same but the experience is much less stressful.
