Over a week without cycling (and visiting parents eating all the tasty food in sight) and I'm already feeling fat and unfit
How did I survive with no exercise before I started cycling, can barely imagine how unfit I was back then and I wouldn't say I was particularly fit atm anyway.
This is why being a runner as well is better than just being a cyclist. Much easier to nip out for a 5 mile run when time is tight or you are away somewhere.
