Core competencies

This month's Runner's World ran a story on core fitness that illustrated the various muscles that, when developed, enhance a runner's performance. The other side of this is the injuries that are likely to occur if a runner fails to condition properly. I decided to try the 15 minute workout to gauge the impact and to see if it isolated muscles that I've, ahem, neglected. I was pleased to see that not only was the workout (5 exercises) possible to do in 15 minutes it was more relaxing than arduous. The article had very clear illustrations and provided guidance on how to ensure you were doing it correctly. They even suggested ways to make it harder. Maybe next time for that.

After the core exercises I was very energized and decided to do a medium long run. We're going to a family event tonight and I didn't want to be too tired to socialize (admittedly, I have trouble in that area under any circumstance) so I cut my run a little short of 4 miles. The good news was the core exercises provided a great lead in for the start of my run. No "stage 1" struggles and the first mile came so fast I had to check twice to make sure I wasn't misreading the display. The bad news was I grew very tired around mile 3. I kept on telling myself the glycogen boost was imminent I just needed to hold on but the boost didn't come. Being slightly insane I constantly calculate my pace by looking at the time and mileage on the treadmill and the mileage on the Sportband. That's a lot of math to do in real time but it gives me a good distraction. I can tell if I'm losing steam when the mileage numbers on my Sportband (which is tied to stride and foot speed) and the mileage on the treadmill (a constant) begin to diverge. That happened around 3.1 miles (at least I hit 5K at intended pace) and I barely managed to run another half mile before I slowed to cool down.

So I think I will integrate the core exercise workout into my fitness program but it's going to be difficult to find the time to do it consistently. Perhaps I can do it at night although my time after I get home from work is already short. Well 15 minutes isn't a very long time so I can't make excuses. The energy boost you get is worth the effort.
