Averaging 50 miles a week so far this year, up to 130 this week (80 on road, 50 off), will be 170 if I can get my arse out of bed and do another commute, have ridden every day for a week (for the first time this year).
Generally though I get in one reasonable lenght xc ride, 8 miles across fields and through woods to some decent trails, 90% off road, which totals 25-30 miles. A long way to the pub ride on a Tuesday night, 15-20 miles, then one, two or three commutes a week, 40-120 miles.
