Can Choosing The “Right” Friends Improve Your Fitness?

While you can’t choose your family, you can choose your friends and science tells us that you better choose carefully. Numerous scientific studies demonstrate that your social circle affects more than which post-run brunch location you go to. Your social circle also affects your health. Perhaps the most famous of these studies is a 2007 study published in the prestigious New England Journal of Medicine entitled “The Spread of Obesity in a Large Social Network Over 32 years”.

2015 Marathon Nutrition Q&A w/Matt Laye

Big thanks to Matt Laye for answering nutrition questions from the New York Flyers‘ Marathon Training Program. Members of the group submitted their questions as they prepare for their fall marathons.

MTP:  I have been throwing up and feeling sick in my last two marathons after mile 17. I drink water every couple miles but i start throwing up in the later stages. I take GU every couple miles that I take in training as well.

Matt:  A couple things could be going on. 1) You may be drinking and eating TOO much. 2) You may be running too fast for your fitness or much faster than your normal training. Each of those could cause your body to divert blood from your stomach to your muscles, which can lead to nausea.
