OK, my total was 17.5 hours less than my goal. Not too bad, 82.47 hours for 3 months. I was sick part of the time, which accounted for some missed days and I did not have the opportunity for as many long ski/snow shoe days as in snowier winters. But, I am not sure I could do 100 hours in 3 months at this time of the year. I am also taking a full 2 rest days some weeks.
I think I can do 100 at the peak of the cycling season, though.
