Jess, the break was one hour 2 years ago because we started 1-hour late because of light. Maybe that's what you're thinking of.
It was supposed to be 2 hrs that year too. A late thunderstorm the night before the race left debris on the track and they shortened it due to clearing the track. Race still had to end at 10pm. Don't know what you mean by light though. I was there racing and having only one hour sucked. What class did you run? How did you finish?
