just tours really, maintaining fitness
i really only cycle to tour, but do longish day rides (~50 miles) now and again in summer. i hate winter and do an odd 10 miles a week, just a bit of commuting/shopping. having done 3 tours this year and i wondered what it would take to maintain a level of fitness so that i'm not starting from scratch next spring; a 20 mile brisk ride once a week perhaps? or is so little a waste of time and effort?
