The last time I clocked my 5 miles, it took me a little over an hour to complete the loop, which is okay. Eventually, I hope to increase my endurance, distance and speed so that I'm running more than walking and so that it takes less than an hour to complete 5 miles.
A friend told me about a 5K race in which she was walking. I agreed to walk it with her. She's much taller than I am, with much longer legs, so walking at her pace might have been challenging had I not been doing my weekly 5 miles.
For those who don't know, of which I was one until recently, a 5K is actually 3.1 miles. I knew that, in theory, but the reality of doing this 5K race made it clear to me that I'm in better shape than I thought. The 5K actually felt pretty easy.

I did a 5K. I have the shirt and number bib to prove it.
I want to do another. Then a 10K. Then maybe a half-marathon and, ultimately, a marathon.
