I must say that was one of the toughest 25 mins of my life, very painful indeed, It was like my legs were running in treacle and getting no forward momentum
Now my legs are very stiff and painful to walk, i THINK i will stick to cycling
He he - well done George. I restarted running in January this year and though I'm off exercise while i wait for more news on a wonky knee, I miss the running waaay more than the cycling. Someone as fit as you will quickly see big improvements - go on, have another go
