When I started c25K, I ran in the clothes I had already. The first several weeks, I was running big cotton shirts and long, heavy cotton, flare-leg yoga pants. Oh, it weighs me down just thinking about it.
Once I realized that this “running thing” was going to stick, I invested in some “real” running clothes. Y’all…the first time out in my new duds, I felt like I was 5 pounds lighter.
If you shy away from shorts like I do (am I the only person who has shorts ride up after taking 2 steps?), consider a running skirt.
