Marathon Night Changes

Due to some timing issues at the previous Marathon Night, we've made some minor adjustments to the night's schedule in order to fit everything. The main change is moving the madison into the middle of the program, to allow us to get going with things straight after warm-ups and some shortening of some of the events. here's the new schedule:
C Grade 24 lap Split-Scratch
B Grade 24 lap Split-Scratch
A Grade 30 lap Split-Scratch
Madison 30 Laps
C Grade 30 Lap Points Race
A/B Grade** 70 to 100 Lap Points Race(sprint every ten)*
*Race distance will be determined by field size:
14 or less riders = 70Laps
16 riders = 80 Laps
18 Riders = 90 Laps
20+ Riders = 100 laps
** A and B categories will split once 25 riders are reached. B race will be 40 Laps, A race will be 60 Laps, both will sprint every 5.
