I used to race, Scottish Masters xc, First season 10th ish after just riding the mtb a lot. Second season into the top ten, now with more structured training – intervals, hrm, etc. Third season podiums! after a winter of road training, Majorca training camp, diet, etc, etc.
Averaged 8 odd hours a week, 3hr sunday, 2 saturday, 2 evenings on turbo, 1 on mtb with lights (winter).
Now got two young kids and self employed, so just ride when I can for the fun of it.
Mind you, would like a crack at the vets one day!
