Ricky...There are no guidelines at an R-100 as to speed or anything like that. No one will ask to see or check your equiptment. Shoot what ya brung!!! As for times...it all depends on the crowd. Last year in VT, Jen and I blew through the Safari side in under 3 hours. This past Saturday, it took 4 of us about 6 1/2 hours to shoot the 50 target Safari side, And about 3 1/2 hours to shoot the North American side.
As for shooting 100 in a day, people do it. Get there early!!! It's gonna be a long day to shoot 100. We had a couple target we waited 20 minutes to shoot. Expect a long back up at the "Apple buck". Lots of people looking for arrows!!!!
I didn't have that problem though!!!
