you can do a few things.
Pro
expert
sportsman
or
Run everybody together then seperate by times.
I came up with a cool format we where thinking about trying at hx
run everybody together top 32 run pro top 8 go to the A - main
33 - 39 are in the A expert 32 total and then the same for sportsman. here is the cool part.
you bump 4 from each main then when the A-main is set you have a 5 min race to set the main how ever they finish is how the A is set. Same for all classes. Just pick a total like top 60 or something for each class
What do Ya'll think?
