Covered up and feet up

The area I covered up with leafs was around 25ft x 21ft so quite a few barrows of leafs,once I'd finished covering the ground with leafs I have to sit down. I must of moved over 30 wheel barrows full of leafs,and the section was in the middle of the allotment. So must of walked 80ft + to the leafs then the same distance back again, so i had to put feet up for a cuppa before i fell down.
