Nutrition & Health

I’m racing the Leadville Trail 100 this August. I live at sea level, so I’m thinking about renting an altitude tent to get ready. I’ve read mixed reviews so far about their effectiveness. Do altitude tents really work?

You know how good you feel after a run? Can my dog get that, too?

Without fail, I have to use the restroom sometime during my morning run. Why is that? And is there anything I can do to keep it from happening? I’m afraid to go on group runs because of it.

I know I need to drink plenty of water when I’m working out in the heat and sweating up a storm, but when I exercise outside in the winter I don’t sweat as much or get as thirsty. Is it still important to stay hydrated in frigid temps?

Can high levels of endurance training lead to irreversible heart damage? A new report is giving athletes panic attacks.

Maybe you should get a checkup before you go the distance

Scott Jurek said he breathes through his nose while running easy because nasal breathing "lowers one's heart rate and helps brain activity." Should I be breathing out of my nose instead of my mouth when I exercise to improve my performance?
