It takes me about an hour and a quarter to mow my lawns. That weekly task is harder on me than my running. I can run for two hours and not be as tired as I am after finishing my lawns.Tomorrow I have to edge my lawns and spray for weeds. Then, the next day I have to fertilize my lawns, and that means my mowing next week will be even harder.
Unfortunately, mowing lawns can't be postponed very much, regardless of rest weeks :(
