I just discovered that 5 kilometers is not 3.2 miles like I previously thought. It's only 3.1 miles!
It may not sound like much but when you are try to run, one tenth of a mile is huge.
With this little bit of knowledge, I feel like I just received a teeny tiny little present today. Although I'm sure once my husband reads this post and gives me a hard time, I will be wishing that I kept this tidbit of info all to myself.
