Formerly just_fixed
i'm 42, fat (18 stone) and reasonably unfit. some of my placements are 52 miles a day 5 days a week with over a thousand feet of climbing. i do it in any weather. my current commute is only 32 miles and a thousand feet of climbing...i'm doing it fixed gear on 65". so just man up young 'un.... 

.....i get down to 15 1/2 stone whilst cycling that far and build up a massive appetite (according to calories used calcs i'm using 5000 extra calories a day) then when i'm finished i carry on eating and not cycling as much.....hence the 18 stone.
