Over the years, I've often got bored of types of riding. Just recently I found myself getting bored of the sort of cycling I've been doing for the last 8 years or so ( long distance / stopped starty / sight seeing ) sort of riding, so I started chucking my bike on the train, going to places I'd normally just touch base at, and then start the return leg, and riding new, shorter courses, in places that I've not really explored much before, then sticking the bike back on the train, and going home. I'll limit the distance rides a bit more for a while, and stick to just a couple of 100 - 150 milers a month. There are plenty of other things that interest me, other than cycling, and I imagine I'll drop back to mostly short, commute type rides, with the odd mid mileage weekend trips within the next couple of years. There are a lot of off road type courses right near where I live at present, so I may get a dedicated mud plugger, and start driving it up to the trails, and back again.
