Bill,
Ours races are 15 mins + 1 lap which usually results in 8 - 9 laps...
Between practice, qualifying and the actual races, we had 10 15min sessions over the weekend....I was totally wiped out by the end of the weekend....It takes an extreme amount of concentration and energy as not only are you concentrating on your lines, but you also have to be aware of where people are postioned on the track around you as there are people trying to pass on either side of you..
As much work as it is, it's also alot of fun...
