Who’s up for Cowboy Tough? In conjunction with the State of Wyoming and the City of Casper, REV3 Adventure is excited to present year three of the 3.5-day Cameco Cowboy Tough Expedition Race on July 16-19, 2015. As in year’s past, this race will challenge both experienced and first-time expedition racers’ physical and mental endurance, all with a spectacular backdrop and a fun and impressive supporting cast of characters. The 2015 course starts in the city of Buffalo, located at the foothills of the towering Bighorn Mountains, and passes through at least two working ranches, so the theme for year three really brings out the “cowboy” in the Cowboy Tough. We’ve added optional points to challenge elite teams both physically and navigation-wise, and  our mandatory points will highlight the best parts of the course.  Once again, teams will take on some of Wyoming’s most challenging back country. Expect mountain biking though technical single track, fire roads, and flowing trails, with plenty of ropes work, trekking, and paddling on your way to the finish line in Casper. We know you’re buff…but are you Cowboy Tough?

You can see some of the highlights from the 2014 race in this video clip.  Video

Race Summary

Each day of the race will be broken into stages that will take between 16 and 24 hours to complete. The stage must be completed in a prescribed time to avoid being short-coursed or having points deducted. Teams will be held at the end of each stage at a transition area (TA) called a “Dark Zone” before being allowed to continue to the next stage. Mandatory points must be collected between TAs. Optional points collected will determine who will ultimately be crowned winner of the Cameco and the City of Casper Cowboy Tough Expedition Race.
For elite adventure racers, there will be adequate optional points to keep you racing nonstop for the duration of the race. For teams out for the experience, collecting mandatory points will push you to your limits but also allow for recovery and rest during the “Dark Zone.”

This is a non supported race.  REV3 will transport a transition container for each team member in the mobile TA for resupply.

    Mandatory Gear: Most of the mandatory equipment is required to help you complete the course safely in the event you have an emergency or mechanical issue. Usually the longer the race and the more time you spend on the course, more equipment is needed to do this. The mandatory gear also plays an important part of our overall safety plan for all the events.
    While biking each racer must also have: You will need a mountain bike for all bike stages of the race. Cyclo-cross bikes are permitted but not recommended. Ideally the mountain bike will have front suspension. There is a mix of single track, gravel fire road and pavement. Depending on route choice, the terrain will vary. There will be a section of mountain biking on single track. The single track section requires little technical skills but will involve some short steep climbs, loose surface, and small obstacles. You only need to have the bike equipment while on the bike. Bike shoes and helmet can also be stored with the bike. Your bike must be equipped with a rear blinking light that must be on at all times when you are riding on public roads. Front lights that have a minimum run time of 12 hours are also required.
