I guess I thought this was kind of like the American Cancer Society's relay for life, where you have a team of people and always someone out on the track (at least my team always did that, most 2AM shifts it seemed that we were one of only a few teams with the whole 24 hr concept.) We had a tent set up and could sleep if we wanted, chairs to sit around and hang out when it wasn't our time to be on the track. So just like that, you have a team and you take turns being out on your bike, rather than running on the track. Some teams could be one person, or 10 people. Again, that was just the way the relay for life was when my friends and I used to do it.
