Figure you'll be there most of the day. You need to be there before 9:30 at the absolute latest -- 8-8:30 is better. Driver's meeting at 10...first car off by 10:30...6-8 runs translates to 4-5 hours of run time, plus lunch...we're normally packed up by 4pm. In addition to driving, you'll have to work a run group as well, so it's a full day.
