I've been riding my hybrid regularly for the past couple of months and now do regular outings of 30+ miles, which I'm pleased with as I've only recently started cycling. I got a new mountain bike on Tuesday as there's lots of fields, farm track and forestry roads near where I live. I took it out yesterday and did my regular run of 32 miles on cycle path alongside loch lomond to get a feel for it. My time was around 10 minutes slower than on my hybrid and I felt I had to work a lot harder,although I did still enjoy the ride. The muscles just at the top of my bum feel a little tired and sore today which I've never had on my hybrid and doesn't feel like saddle soreness. The mountain bike is a 29 er so bigger wheels than my hybrid. Is it simply the difference in rolling resistance between the 2 bikes that means I've had to work harder or do the 2 bikes require different muscles being used?
