Training isn't just about banging out the miles. It also applies to what works for you regarding diet, stretching, hydration and many other factors. For example I was struggling with my early morning runs on a big bowl of porridge. I changed it to a couple of slices of toast and that made a huge difference. Try to see what works for you and if you have a bad run at least you know what to change.
As far as my running is concerned after 40+ years of running, a heart attack exactly a year ago has made me start from scratch. You don't realise how much fitness and muscle mass you lose over a year, especially for an old git like me.
Kudos to those who have just started running, stick with it. When you do get fit, running it's dead easy. Nip out for an hour, home and quick shower, a great start to the day.
Anybody else do the Lyme Park parkrun? 400 feet of ascent puts hairs on your chest!
