Have you ever run a marathon?

I did one and that was enough. The cardiac conditioning was fine but the training and the race itself took too much of a toll on muscles and joints. I battled cramps on my long training runs and in the last 5 miles of the race itself. Wanted to do it in 4 hours but it was more like 4:20. It also took me forever to feel I could run normally again after the race. I’m much happier with half marathons.
