This is the boring jobs conundrum. All jobs are boring in their own way, whether it's transplanting hearts or mowing lawns. Same with bike rides, they are all the same and at the same time all different, because I'm a different person, and I see, feel and remember different things each time I ride.
Lots of diyers have their own routes they ride each month for their RRTY. Its not necessarily about the route, the pleasure of being out for a days relaxed riding can be enough. I rode the Ditchling Devil six times in 2011, purely on a 'wake up, nice day, go' basis and it remains my 'go to' route.
What I rebel against is the turning of the seasons, the calendar which would dictate what and when I ride and makes me yearn for pastures new. I suspect that's the real complaint.
