The races will be approx 50 miles. I have lap counts on the OP.
Looks like getting the times sorted is going to be the most difficult thing for us. As is the way with most leagues. I'm chewing on a couple ideas about how best to address this.
How about this: 1 race on Tuesday's around 8pm EDT, 1 race on Fridays around 9 or 10pm EDT and 1 race on Saturday around 4 or 5pm. Those are examples, we could swap days/times, but I'm thinking those 3 time slots will fit drivers from Europe, East Coast US and West Coast US. I'd could host the 2 earlier slots and one of the alternate hosts could run the later time slot, and I have no problem with the drivers who need to run in the later time slot working out a day/time amongst themselves that works best. I'd still do all the record keeping and administrative stuff for all 3 nights, the alternate host would just have to make sure everybody plays nicely and then send me the final results (cell phone picture of the results screen would probably be easiest.)
