I average 200 - 225 miles a week. I'm 55 and have ridden for about 33 years now.
Five days of commuting a 20 mile RT. Usually ridden at very high effort except on Friday in preparation for the
weekend.
Usually a club ride on Saturday, anywhere from 70 to 100 miles. I ride a 23 mile round trip to the ride start location so that ups my mileage. The day's effort depends on the route and the group mood.
Sunday, a shorter ride, never less than about 45 miles it seems, effort level is intense if ridden with the club,
a bit lighter if solo miles.
I live on a pretty good sized hill so EVERY ride has at least one noticable climb.
