  1. We love dogs, cats, parakeets, and your pet goldfish just as much as you, but they won't be allowed to join you at the races. For a few reasons: one of which is that some of the land we race on are working ranches, with strict no pet rules. 

  2. Pacers are only allowed on the second half of our ultra distances. A pacer is only there for motivational support and safety, and thus cannot be used as a mule to carry any of your food/water/gear. 

  3. You get a finishers medal only for finishing. We have some amazing hand-made, recycled wood medals that we will be thrilled to throw around your neck...but only after you cross that finish line. And earn it!

  4. We can't give refunds or transfers. Once you purchase your race entry, we pay the land owners for your park pass, buy your t-shirt or hat, pay the insurance company,  pay the timing company and photographer,  and on. That said, we're still very reasonable people and want to help you out. If you write a compelling request, we'll give you a discount to a future race.

  5. No cutting the course (ie CHEATING). Some days just aren't your day to race well. Realizing and respecting that bad race day by dropping out is WAY cooler than getting caught cheating. Oh, and if (when) we catch you, you will be asked to not race with us again. Ever.

  6. We prefer you run without them, but if you're going to wear headphones, use only one earbud or turn it way down. You have to hear people trying to communicate with you. We have had a runner take off in the complete wrong direction just because she couldn't hear us screaming at her to stop. Her loss.

  7. Most of the trails are single track or very narrow, so get used to saying "ON YOUR LEFT" when you pass. It also never hurts to tell that person something encouraging like, "NICE JOB". And while you're on a kind streak, a big "THANK YOU" to the volunteers is golden and earns you an extra beer.

  8. If we have to postpone the race due to weather, we will push the race back to that afternoon or into the next day. We aren't afraid of a downpour, but we don't mess with lightening or hurricanes...or Sharknato.
