Desert Challenge (8/11/23)

Calico Racing

Back by popular demand, and reincarnated at a new venue since 2016 to bring you a new challenge! Pure Mojave Desert running at its finest! Come join us on this PAVED and scenic course which covers rolling terrain.

Commencing at an elevation of roughly 4500 feet, runners will experience high desert vegetation to include Joshua Trees, Pinion-Juniper, Mountain Rose, Sagebrush, and a relatively lush Toiyabe National Forest not commonly associated with Las Vegas. The road twists and turns thru the canyon; a true treasure of the Spring Mountains N.R.A. enjoying temperatures ~10 degrees cooler than the Las Vegas Valley.

Still an extreme heat race, expect daytime highs ~95- 100 degrees and overnight lows ~75. On course provisions will help keep you cool!

Choose from morning or evening start times!

B. K. from Alberta, Canada (7/6/2018) "I think I saw the Devil..." (about: 2018) 50+ previous marathons \| 1 Running With The Devil Marathon COURSE: 5 ORGANIZATION: 5 FANS: 3 This event was a real 'Race with the Devil'. It was hot: 27C (81F) at start and 41C (106F) at the finish line at high noon. The course was out and back along Lovell Canyon with a double loop near the half-way mark. Pavement all the way and clear sky with almost no trees to offer a shadow. There were many hills with one steep, long section in the middle of the road. The water stations and volunteers were high above average: there was ice and ice-cold water, drinks and high energy snacks. In summery it was a small size event which gave me huge satisfaction. Thank you!
kirk walker from nevada (6/24/2017) "Great marathon in every way" (about: 2017) 11-50 previous marathons \| 2 Running With The Devil Marathons COURSE: 5 ORGANIZATION: 5 FANS: 1 What a great marathon. The course is awesome and beautiful. There is one hard hill at mile 20 to give you a reality check. Joyce, the race director is wonderful. 45 minutes from Las Vegas, with great vegetation, (trees, desert, huge views. Wonderful volunteers.
M. L. from Vegas (7/12/2016) "Hot, challenging course with no spectators" (about: 2016) 50+ previous marathons \| 1 Running With The Devil Marathon COURSE: 4 ORGANIZATION: 5 FANS: 1 I've run this course 3 times but this was my first time at Running with the Devil. It is a challenging out (uphill) and back (downhill) course, plus its hot in June. The race had plenty of water and ice (ice ice baby) on the course! I didn't run fast but I still had a good time.
Ariel Hessing from NJ, USA (1/19/2013) "Hot sun; 5% humidity; 0 wind; rolling hills." (about: 2009) 11-50 previous marathons \| 1 Running With The Devil Marathon COURSE: 4 ORGANIZATION: 5 FANS: 2 I ran the 'Running With the Devil Marathon' in 2009 when I was in top shape. If you're running for a fast time, pick another race, cause this ain't it. No humidity, but the sun and hills will slow you down. Drink often!
P. C. from United States (6/26/2011) "Hot, Hilly...but NOT Humid" (about: 2011) 50+ previous marathons \| 1 Running With The Devil Marathon COURSE: 5 ORGANIZATION: 5 FANS: 3 Now THAT was one TOUGH marathon! First half run very conservatively. Second half the unrelenting and in my opinion HUGE hills made me feel like a rag doll going up them. Oh and the 100 degree heat was not a big deal as the course had a perfect amount of well stocked and well iced aid stations. Really enjoyed the event from the host hotel, the Hacienda in Boulder City, to the race management and fellow competitors. This is another one of those little gems of a race worth doing if HUGE hills and Massive heat does not scare you. Three cheers to Calicoracing for having the courage to put on this wonderful event.
T. G. from Albuquerque, NM (12/8/2010) "A lot of hot hard fun!!!" (about: 2010) 2 previous marathons \| 1 Running With The Devil Marathon COURSE: 4 ORGANIZATION: 4 FANS: 3 I thoroughly enjoyed this race. It really pushed me and was just crazy! I don't know what I would've done without my darling assistant!!! Heheheh. A word of advice: keep dumping ice water on your body. I started to get a little exothermic and keeping my body cool made all the difference. Thank you, Mary....
Kelly Mercer from Las Vegas, NV (8/10/2009) "It was hot, but the hills were hell." (about: 2009) 2 previous marathons \| 1 Running With The Devil Marathon COURSE: 5 ORGANIZATION: 3 FANS: 2 This was my second race, and the second full marathon I have ever run. Being from Vegas, I had the advantage of doing a lot of heat training before the race, but I wasn't ready for the hills and heat combined. I had to stop at every aid station to put my gear in ice water and fill my two-liter Camelbak up, since it would almost be empty. I ran the entire race wearing a devil horns, a tail, and a pitch fork (which gave me a good bicep workout). The asphalt was so hot that my feet were burning for the last 10 miles. After the race, my feet were covered in horrible blisters. It was definitely an experience I can brag about.
C. G. from Tyler, Tx (7/15/2009) "HOLY COW!!!" (about: 2009) 1 previous marathon \| 1 Running With The Devil Marathon COURSE: 5 ORGANIZATION: 4 FANS: 1 Being from East Texas, with its HUMIDITY, all I can say to those who say, "But it's a dry heat": come on and give this one a try!! I have one other half-marathon under my belt and the temp was 42 degrees. This was a great challenge. Make sure you are ready for HILLS and HEAT. I trained in the humid heat and that helped, but I was unaware of the length and grade of the hills. Aid stations were great, though the next to last one ran out of ice, which I really needed. They did run out of t-shirts too, but I registered late. There was not much in the way of crowds cheering; it was only you and the Mojave Desert. Good view of Lake Mead. (Who would want to stand out in the heat to cheer you on anyway?!) Very little hoopla at the finish line. Would have liked to see more of a "welcoming committee" after finishing such a race. An awesome challenge - not for a PR. DO NOT DO THIS RACE WITHOUT TRAINING FOR THE HEAT! If you do, you may get to meet the local EMS.
A. B. from Killeen, TX (7/4/2009) "Some like it HOT!" (about: 2009) 1 previous marathon \| 1 Running With The Devil Marathon COURSE: 5 ORGANIZATION: 5 FANS: 3 This was my first experience with the "Devil." This race offers a great view and a great chance to challenge yourself mentally and physically. If the hills don't do you in, the heat will - and vice versa. It's not a course for PR's or fast times, but rather a demanding challenge for those who love an adventure. The race director, Joyce, is great and friendly. The people who ran the race with me were kind and friendly too. The entire course is pavement. There are cars on the course; it's not closed. You need to bring a good 24-ounce water bottle with you or a Nathan Camelback. Bring your sunblock too! You'll need it. I suggest wearing a hat and sunglasses as well. Wear socks that are thin and won't blister your feet. Train on hills and in high heat for this one. Don't come under-prepared or you'll be walking up several hills! I had a great time at this race and I would definitely do it again!
J. T. from Utah & Brazil (7/3/2009) "Notorious for breaking strong athletes!!!" (about: 2009) 11-50 previous marathons \| 3 Running With The Devil Marathons COURSE: 5 ORGANIZATION: 5 FANS: 4 What can I say about Running With The Devil other than that it is as difficult as the name sounds?!?! DO NOT ATTEMPT to run this event unless you are serious about pushing your limits in extreme heat conditions and desire to learn what can happen to your body and mind in the most devilish of marathons and ultra marathons! The organization and structure for the event is always near perfect (I've run the 50 all three years, 2007, 2008, 2009) and never had reason to complain about the race itself, even though I've had to drop (literally) all three times - at 36 miles in the first year, 28 miles in the second year, and 41 miles this year. Some finish, usually about only half of the field; the rest go as far as their poor, heat-exhausted and dehydrated bodies allow them. It's a challenge like no other, with NO support crews allowed (unless that changes in the future). It's just you, the aid stations, and personal management out in the extreme hot and dry climate of the desert. A "Mini-Badwater," it's been called. I'm a Badwater veteran myself, yet RWTD 50 has shown me that few are capable of surviving it without a support crew in those conditions. I admire those who can handle the heat. I can't... yet I enjoy a challenge, and this one is exactly that. Don't register thinking it'll be a nice scenic run to chalk up on your list of marathons or ultras. Realize that it will truly prove that you don't know your limits yet. - JT
