You can walk in unless you want to go with a group and all race at the same time.
Takes about 2 minutes each person to sign up there. Multiple terminals to do so.
No just walk in and fill out a profile on the computer at the desk and pay with cashier and wait for ur race to be called
Yes you have to sign up and you can do it there as well. Its better to sign and take a appointment to avoid waiting in line there.
