velo a go go

planned to ride the bike to work today but it didn't happen. went for a ride after work instead. was nice. forgot to take the camera so couldn't do a don.

obviously the bike i rode was not the one pictured above.

i'm trying to do either a run / walk / ride / climb every day.

my question is: how much exercise do i have to do before i can eat like a fatty without getting fat?
