A) 2 hours/week for about 6 years = 624 + shows = around 750 hours for the first 6 years of my riding career..
B) 10 hours/week for 8 years = 4160 + shows = roughly 4500 hours
C) this summer was riding for 8 hours per day at least for 5 days per week for 4 months, plus training for 2 months on either side = approx 750 hours
Umm, so a very rough estimate: 6000 hours... that doesn't seem like much, cosidering I've been riding for 15+ years... I'll have to go over my numbers again when I'm more awake...
