dunno, only keep a rough track. basic commute is 80miles a week, then a few rides a week on top of that. Summer mileage (with more light, drier faster trails) tends to be more. Pretty rare to do less than 50miles on a sunday in summer (50miles in warwick might be easy, 50miles in the brecon beacons is pretty hard ;D
3 years ago me & curly did cwmcarn to penyfan (2950ft highest point in s.wales & s.england) & back. its around 85miles with 17K ft of climbing. Think I did that ride 4times in 05. Got a monster 120mile route same as penyfan, but coming back via the black mountains & sugarloaf. looks around 21K ft of climbing. I reckon around 12-13hr ride.
If anyone doesnt believe me, you're more than welcome to meet up with me & my boys for a ride any sunday
But hey, as long as you're having fun yeh
