just upped from 15km/9.4miles to a new route of 18.5km/11.6miles, twice a day, every day. But probably only 50m change in elevation, so not too bad, but along the coast is often windy as, so not always easy riding into a headwind alone…
Road/commuter monday to thursday, friday I finish early, so will ride the MTB in then head the opposite way from home to the hills for a lap of the trails before riding home; that can make for a 60km/37.5mile ish day.
then throw in a ride or two over the w/end (usually a decent MTB, maybe a gentle road recovery ride, although often the recovery is a long beach walk or sea swim in the summer when the ocean is warm enough for variety and to get a break from the bike) and I easily get over the 200km/125mile mark for a week. Does take a bit of getting used to, but through gentle, progreessive overload I'm getting a heap stronger, fitter, more comfortable on the bike which is good as long rides are what interests me, not short, sharp racey bursts a la XC racing.
