I struggle to run now. My natural stride, what I’m comfortable at, was my old normal pace of 7:30 minute miles (8 mph or 12.9 kph or 4:40 minute kilometers). And that’s where the muscle memory wants to put my feet. Except I don’t have the lungs or the muscles to do that for more than a minute or two without getting spent.

I know if I want to get faster again I should just train, but my heart just isn’t in it at the speeds that I have to go.
