Why I Haven’t Run a Second Marathon Yet

I don’t enter races very often, but over the years I have run in many 5ks, a 10k or two, a 15k, and several half-marathons, and one full marathon.
What made my first and so-far only marathon possible was a confidence that I could run 26.2 miles, despite never having run even close to that distance before. It took me two years to complete my goal, but I just knew that I could do it.
