I'm 57 years old and race in the Forward Motion Hare Scramble series, (Kansas/Missouri, Senior class #1017). I only race 2 or 3 events a year anymore and it's mostly fairly tight woods, and a scramble is 2 hours long. . Like the other guys have said, limit your caffiene the morning of the race, and start hydrating alot a few days before the event. Be carefull what you eat the night before. It's very important to settle into a pace that is comfprtable for you. I usually ride at about 85% of my true ability which leaves a little left in the tank when I come across someone in my class and have to battle with him, or have to pass slower riders and have to work to do so. On your sight lap, look for potential cut lines, (legal) you could use if you come across a bottleneck. My goal is to never stop and I rarely do. Sometimes I may barely be moving after a nasty creek crossing where I might get stuck or have trouble, but I try to keep going. Pace yourself and you can always pick it up a bit as you move thru the race if you feel like it. I ALWAYS feel like I've been run over by a truck after the race and especially the next day at work, I'm damn near an invalid, but racing dirt bikes is some of the most fun I've ever had. Good luck. and report back how you did.
