Tomorrow at 0700 I will begin a 20K trail race. The 20K isn't the issue as I run all the time anyway. The deal is that it's a TRAIL race. It takes place in my favorite place, Mission Trails Regional Park. The race starts easy enough, nice flat grasslands, for about 1.5K then goes up and up for another .5k (Kuaaypay mt.) then down the other side. back across the grasslands then at 6k it's up, up, up again between the North and South Fortuna Mt. (The Saddle), down the other side. THis is no joke it's REALLY steep! The mountain bikers nich-named this portion "ball bearing hill" The last time I was there, I got to the top, kicked a rock AND IT ROLLED BACK DOWN THE HILL!!! Then at 12K the hard part starts, The trail goes UP the South Fortuna Mt. Down the other side and back to the Saddle. Then the rest of the race is back through the grasslands and is relatively flat (thank god). Anyway, If you don't want to do the math 20K is about 12. some odd miles. But again, it's not the miles...it the up and down hills that's gonna suck buttermilk.
