Used to be a 25 km to and from work, plus group rides after work and on weekends. Guess around 200 km per week. But not 200 miles. Not intensive at all, but I do ride all year long. When it snows, it's an old rigid MTB with studded tyres.
Road bike was used very seldom, but the more I rode it, the more I liked it. Soon I put a rack on the back and used it as a fair weather commuter. Now I'm thinking of getting cheaper spare parts (hence 8 speeds) and riding it all year long. It's lighter, faster, more fun, better seating position...
