I ride unpaved paths but try and go as fast as I can - it is my nature. Unfortunately that is a little slower this year after having some stents put in. But I just love the cool mornings riding in, up with the birds, hawks, and occasional deer or Coyote, and can take a longer path home, depending on the sunset time. But I got just one speed and always look for another rider to motivate me more
I get into work earlier, even though it is over a half hour to 45 minutes longer to ride in than drive - I am more motivated. Get a nice shower after cooling down and I am more productive and focused for the day. Overall, with a 2-2.5 hour RT commute, I get a free hour and a half of exercise!
