Anyone can enter. Qualifying is only to seat top riders from other races into the final race on Sunday. You can qualify by setting a fast qualifying time on Saturday and/or by finishing high enough in the standing on Sunday's morning race.
But no matter what you will have to complete the Sunday morning race in the allotted time to be able to start the Sunday afternoon race. The winner will have the lowest combined time from both Sunday races.
This format, we hope, will allow anyone a chance to come out and show everyone how good of a rider they are with a course that will get progressively more difficult.
I always say, "Don't tell me, show me." See if you can qualify. See if you can finish.
