While victory in an AMA EnduroCross (EX) race might not depend absolutely on a great start (given how the radical obstacles that litter each course make it impossible to have a mistake-free race), being up front in the first turn never hurts.
But optimizing your start begins before you even line up, as off-road legend and EX Veteran-class champion Destry Abbott points out. Notice little things like if there’s a hole right after the gate or if the direct line to the first turn isn’t from the inside gate. Once you get that handled, then you can concentrate on the rest of the starting procedure, which is similar to how you would do it in a motocross race, except you’ll likely be in second gear the entire time.
