I do not recommend running a marathon on short notice.
I will never do that again.
But do I regret it?
And if you told me you wanted to try it, I wouldn’t talk you out of it either. If you’re an experienced runner and have run a marathon or two before? Go for it.
With that said, it’s obviously best to run a marathon when properly trained – but if it weren’t for the fact that I went into this under-trained, I probably wouldn’t have investigated the run/walk approach to a marathon. From where I sit now, I’m very grateful I had a reason to try it.
