Recently I signed up for my first 5k. I've been walking and running for about 10 years. Some young friends talked me into trying it. I started slow, and in my 'much older' sisters words, I just tapered off. I decided I was never going to get faster and if I didn't try to finish a 5k now, I'd never do it. I guess my impending 60th birthday is making me feel like I need to 'do' something; something I can say, "I always wanted to do that!" So a few days a week I get my workout clothes, my 49ers cap to keep my curls out of my face, and turn on my Nike running app. I don't always feel like doing it. Sometimes I hurt, or I'm tired, or I just have too much to do. I want to give up. But when I make myself keep going. . . one foot in front of the other, tired legs or not, ragged breathe. I always feel better at the end. I know that powering through the difficulties will make it worth it in the end. This made me think...
