Have you ever tried to do something that you thought you’d never be able to do because it was too hard?

I have. Er, I mean, I AM.

If you follow along on my personal blog, Suburban Scrawl, you know that I have been in training for the past eight weeks to do my first 5K, which will be at the BlogHer conference in New York City, in less than two weeks. I don’t consider myself a runner. In fact, before I started this training, I hated running.

Truth be told, I still don’t like it very much. However, being a group cycling instructor, I enjoy the running a *wee bit* as way to cross-train, because frankly, parts of my legs awakened when I began running, and I never even knew they were asleep!

One of the things I really have to be careful about while I’m running, especially on the days when I don’t get my rear in gear nice and early, before it gets hot outside, is drinking enough. I try to drink lots of water (plain AND mixed with Crystal Light Pure Fitness drink mix, of course!) all day long, to keep my body hydrated not only while I’m exerting myself, but for the other twenty-three hours and fifteen minutes, too!

Being a late-bloomer, workout-wise, I never imagined myself even finishing the training that I’m doing, let alone completing a 5K, which of course, I DO PLAN TO FINISH. What’s been most impactful to me during this experience is that I set my sights a little higher than normal, and I’m succeeding. I can. I can. I can.

I will. I will. I will. And I’m proud of myself already, for what I’ve accomplished so far.

What else can I do? Hmmm. Seems to me, the sky’s the limit!
