My dad and I race hare scrambles. I have been running a 150R for about six races since last fall. The first two races of this season, I have been passed by another kid who is riding a 100F. He ran 189th out of 234 riders that finished this week. That may not sound impressive, but his class has to stop after one hour and the rest of us race for two hours. He is still running the Junior class. Also impressive is that all but 5 or 6 other bikes out there are all bigger than his. He bests my times by 2 or 3 mins. every lap. It would be embarrassing, but he is passing guys riding bikes twice the size of mine. The kid is on rails!!!
Gives credence to the saying, "Its not the size of the dog in the fight, its the size of the fight in the dog!"
