Phoenix, AZ: Ironbody of the Month, Megan "IronMom" Keller and Navy Special Forces veteran Steven Casey, complete the single day, Grand Canyon Rim to Rim to Rim hike.

"Every year some 6 million people visitors to the Grand Canyon, less than 1% ever venture past the rim. There are a brave few that hike to the bottom and even fewer that hike from Rim to Rim. There have been maybe 1,000 people or less on the face of this earth that have ever hiked this world famous landmark from South Rim to North Rim than back to South Rim in a single day. This is without question one of the most challenging physical, mental and emotional endeavors one can undertake. Completing this amazing journey is further proof that the Iron90 System delivers superior fitness."
