Mine is a little over 35 miles. Best time is 2 hours roundtrip. 57 minutes in, 1:03 home. Have also done 54 in, 66 home. It is about 12 minutes on a road, 40 minutes on a bike trail, and about 5 minutes through the city. Going home is harder with more uphill, a headwind stretch, and a long light that is hard to catch or break. And then there is the nighttime and winter. That slows the turn home even more. Last night was 80 minutes. I dread the first snowfall becuase they don't plow the trail and I'm forced onto the road for about the first 7 miles, with more hills.

I've been doing it four days a week for the last two work weeks. With an infant at home now and cold weather coming on, I plan on three/week for the next month or so, hopefully 2/week through December and January.
