100 mile mntn bike race--who's done one?

[Anelia]

Hi there, endurance racers!
Today I did a major rehearsal for my race at the end of April. I wanted to check my pacing, nutrition, water consumption or any other issues I might have on a longer race. I rode alone, offroad, I did two circuits of our local race track. My computer stopped working at 72nd km (low battery) but the statistics is about 85 km, 6 hours and 5 minutes, about 14km/h, 2000 m climbing. I did no longer breaks than to pee (once) or to wait for a passing car when I crossed a road. My average pulse was 138 which is not bad for a training but on the race I expect it to be higher.
What I rode today is 2/3 of the distance for the race. Do you think I should ride the whole distance 120 km offroad or the equal hours on road next week?
I did ok with pacing, nutrition and water, I did not bonk. Only my hamstrings hurt a lot but I rode through the pain. My butt was perfect, I am so glad about it
And one more thing to add to the must have list is CHAIN OIL.
