I got my pack today - yay!
I took up the cycling this year because I was spending £40 a month on gym membership, then not being able to workout properly cos the gym was always packed. I stopped smoking 2 years ago and piled on the weight so I want to lose the belly. Unfortunately, I can't seem to give up the pies and fish suppers so, although cardio-wise I'm fit, I'm really just exercising to stop myself getting fatter.
It's been good working out mph and the like just to see that I'm not a total diddy, but I agree that all the different factors mean it's hard to get consistent results. On top of which, if I push myself too hard my knees give me too much pain for days afterwards.
If I do the challenge ride in 3 to 3 1/2 hours I'll be happy.
