The AR World Series unites in competition the world’s best endurance athletes at premiere qualifier events around the globe

In August 2017, teams from around the globe will race across the wilds of Wyoming, USA, in this annual championship adventure race.

“The AR World Championship has waited a long time to come to the USA and 2017 will be the year,” said
AR World Series director Craig Bycroft. Rev Adventure race director Mark Harris added, “It’s fitting that the toughest adventure racers in the world will prove their mettle at something called the Cameco Cowboy Tough. We’re thrilled to be hosting this prestigious event and can’t wait to put on another one of our races for multi-national participants, this time on a world stage.”

“Wyoming’s beautiful and unique landscape has challenged athletes competing in the Cowboy Tough race
for the past three years,” said Wyoming Governor Matt Mead. “The 2017 Adventure Racing World
Championship will allow us to showcase Wyoming and all it has to offer to a worldwide audience. Wyoming
offers incredible outdoor experiences and we are proud to host the Adventure Racing World Series.”

The 2017 ARWC will be Cameco Cowboy Tough’s fifth year in Wyoming. Each year, participants have
raced across a different part of the state, including the Wind River Range, the Big Horns, Medicine Bow, and
Grand Teton National Forest, crossing the finish line in Casper.

“It has been a privilege for Cameco Resources to help launch this series in Wyoming,” said race sponsor
Cameco Resources President Brent Berg. “The message of enjoying our state’s amazing natural resources
while respecting and taking care of the land is an important part of every race week. We are grateful to
Governor Matt Mead for conceiving of this exciting event to broaden Wyoming’s traditional western
appeal.”

Domenic Bravo, administrator for WYOPARKS, added, “WYOPARKS is excited to be a part of this race as
we have been involved with the Cameco Cowboy Tough since its inception. Rev3 Adventure is a world-class
race organizer, Wyoming offers amazing venues, and as we have seen in the past Cowboy Tough is one of
the hardest but most enjoyable adventure races in the country–all of which are a recipe for success.”

The Championship will bring together 50 teams representing more than 30 countries. Participants will have 6
days to cover up to 500 miles of Wyoming’s varied and truly breath-taking terrain. Traveling by foot,
mountain bike, vertical roping, and boat, and following a map with mandatory checkpoints, teams can expect
abundant wildlife sightings and scenery only Wyoming can offer, including vast ranch lands, majestic
mountains, authentic ghost towns, dramatic canyons, and alpine rivers. They’ll race through history over
mountain passes crossing the Continental Divide and along old wagon roads used for the Oregon Trail, the
Pony Express, and the Gold Rush.

The AR World Series unites in competition the world’s best endurance athletes at premiere qualifier events
around the globe. The top two teams at each of these races gain a coveted position on the start line of the
annual pinnacle of the sport, the AR World Championship.

The AR World Championship has defined the sport of adventure racing and crowned the world’s top
adventure racing teams since 2001.
