The grand prize goes to Wagner Araujo, a photographer from Belo Horizonte, Brazil who captured this striking black and white scene of athletes dashing into the surf during a Brazilian aquathlon. Araujo, who will receive a 10-day Galápagos National Geographic Expedition for two, describes his winning photo:
"I was in Manaus, Amazonas, during the Brazilian Aquathlon (swimming and running) championship. I photographed it from the water and my lens got completely wet, but there was so much energy in these boys that I just didn't worry about that."
All the winning photos will appear in the Dec. 2013/Jan. 2014 issue of National Geographic Traveler magazine. Can't wait that long? Continue on for a digital preview with captions provided by the photographers.
