Well after years of never being able to run and with the constant nagging memory of being literally dragged round the cross country course by my PE teacher- I've started C25K so next year (my 40th) I can join my family at ParkRun ! I didn't manage the full 60 seconds every time today, but I had a good go.
The walk up the stairs to bed told me I'd used muscles in my legs I didn't know were there - roll on Tuesday for W1R2 !
