We did a timed ride today -- instead of riding together, my husband and I headed out together for a two-hour ride, i.e., we each rode out for an hour at our own pace and then came home. I pulled the trailer so I made it about half as far as he did, although I also made it back twenty minutes early because I turned back a little early. I did about 20 miles and my daughter did so well ... I keep worrying that she will start to get bored in the trailer, but she just loves going for rides and gets really excited.
