I feel if you pay any attention at all here you know which of us ride at what pace. That said you're never ever obligated to keep up. I'll always wait at intersections for others to catch up and be accounted for but I shouldn't have to slow my pace because someone that showed up isn't happy with it. Ride your ride, I wait at the next turn. Don't want to continue, just let me know at next turn you're pulling off.
Mach Retard and Fast are rides, the other paces are poker runs ?
