Used to love running in my 20's and 30's. 8 to 10 miles 3 times a week round Oldham and Royton. Used to run from my house in Shaw to Hollingworth Lake and meet mates who had driven to the lake and ran around it before getting in their car for the journey home while I ran it. 11 miles all round. Then I ran from Shaw, Delph, Uppermill, up to Grotton, into Oldham centre, past the college, down past Boundary Park to Shaw Road and then home. About 16 miles in total. I used that to eventually run the Manchester Marathon to buy a hospital cot for Booth Hill Hospital who saved my sons life when he was 1 year old.
Now I'm 60 and bolloxed, I couldn't run a bath. I'm jealous of you all, but hope you keep going for as long as you can.
