Weekend runner goes vegan and becomes an endurance athlete

Matt Frazier, a self-described “recreational athlete” went vegan in 2009 and became an endurance athlete who now competes in races up to 100 miles long.

“Plant-based diets give us the best access to a wide variety of nutrients and fiber and those things really help reduce fatigue, increase oxygen and blood flow to muscles,” says Brittany Verras, an Emory University dietician working with athletes.
