I've committed to commuting 3 - 4 days a week from now through the end of the school year. It's just under 20 miles round trip with the AM ride slightly down hill and the ride home a bit up! No real wind issues on the commute but 10 - 12 hours on my feet, before any riding time and the trip home has been a challenge. I'm averaging 16.8 mph on the way to school and 11.1 on the way home. AM commute runs about 33 minutes but the ride home is close to 51-52. Traffic has been easy (I travel opposite the heavy flow) and weather has not been much of a factor.
