Happy Christmas Eve Duathletes!! In the midst of the holiday hustle and bustle, don’t slack off too much on training. One great way to make sure you get it done is to get it done first thing. Morning runs, rides, or some combination leave you energized for the day ahead. And according to a recent study, running may make you more productive at work.

A University of Arizona study shows running stimulates part of the brain related to decision-making and planning. Much like playing a musical instrument, running helps improve memory and attention span. Read more here.

As I write this, I’m about an hour away from a long early morning bike ride. Unfortunately, the study didn’t analyze cycling, but if it did, and it posed similar benefits as running, I will return home able to recite the encyclopedia!

From your favorite Duathlon blog, have a very merry Christmas, Hanukkah, Kwanzaa, or just a very happy week between now and January 1. You may hear from me in the interim. If not, and in the meantime, follow me on Twitter @gorunbikerun.
