our normal rides are every other week.. about 40 miles.. very tight single track for the most part.. last ride we rode 4 hours and only made 30 miles.
i have a month to race day.. not going to kill myself, but some cardio and stretching every day..
for the most part, i am not too tired or sore after those rides, depending..
my pace is pretty much the same start to finish.. i dont seem to use too much energy on the gasser.. if i can keep it up right that is...
