I am developing a noticeable belly. Cycling outside on the rollers is not so appealing in icy weather, and I am finding it harder on hills. Another vicious circle related to the AF. I am doing less volume and intensity of exercise due to the AF. So I am losing fitness and therefore unable to maintain the volume and intensity of exercise, so i am losing fitness.
As I am more and more restricted to flat roads, I have rebuilt my old track bike as a singlespeed cross to allow me more vrieety of park areas. Just waiting for the tyres, 30mm knobblies. They should fit, the bike originally had 27″ by 1 1/8″ tyres. Brakes appear to have sufficient clearance.
