Depends how you sport. In London, my daily 15km cycle to work would have me constantly starting and stopping, sprinting small hills, dodging tourists, racing fellow bikers, brushing cars, and basically being alert at all times for any and all dangers (this was before the mass cycle lanes). There was a weird adrenaline induced rhythm to it that would grant me both physical and mental relief everyday that I had somehow made it to work without dying.

Since I've moved to the countryside; boring endless gentle hills, breathtakingly stunning scenery that offers no challenges, and my brain basically goes into autopilot. I get to work feeling physically fulfilled but mentally drained.
