The commute this morning was cold and "fast?". I found a new route that added a good 4.5 miles to my route that involves a 5 mile steady uphill and 6 miles of rolling hills. I only averaged about 14-15 mph on the uphill but once I hit the rolling hills my speed went up to 19 to 20mph. There are traffic lights but because its so early, 6:00 am, they were mostly green and I was able to keep a good rhythm. Its heaven, in the dark.
