So this weekend (Friday night, all day Saturday), my Tae Kwon Do school was having its annual summer black belt retreat. I just earned my black belt in June so this was my first retreat. The retreat site was a local tree farm where we would be able to camp overnight. A few people -- myself included -- couldn't stay over so were planning to commute to the site both days. When I was driving home on Friday night, I realized that the site was only 8.5 miles from my house. So on Saturday morning I got up and ran to the site, trained with the other black belts, and then ran home. Saved on gas and got in an excellent workout!
