Big Bend Ultra (21st annual)
In 2004, a wild idea was hatched: an ultra trail race in Big Bend. It had never been done. The logistics were impossible. Big Bend national and state parks are huge: over 300,000 acres and several hours from San Antonio. Water is scarce. Fuel is scarce. Transportation is scarce. The isolation also means it has lowest light pollution of any park in the lower 48 states: making it a fantastic place for stargazing. This was the beginning of a truly great event that has been held annually ever since. This year Carroll Voss, Erik Stanley, and the team of volunteers and competitors with Trail Roots are looking forward to the best race yet.

Crew, friends, and family are welcome to cheer you on at the start/finish (Barton Warnock Center). 50 milers will be coming through the start/finish as they complete the 50k loop. There will be a designated drop bag area for 50 milers at the start/finish line.

Race Beneficiaries
The Friends of Big Bend Ranch State Park is a non-profit organization that helps improve and maintain trails within Big Bend. They provide race support and volunteers. We are proud to donate a portion of proceeds to support their work as well as a portion to the Big Bend Trail Alliance.
Volunteer
Volunteers are great way to give back or get credit towards your future races. We rely on experienced mountain bikers as volunteers to help with trail setup, tear down and safety patrol. If you are good with a full day of trails (not terribly tough, but requires fitness and experience) it’s a fantastic place to ride. You must be able to take care of your own lodging, transportation, flats etc. and other gear. It sounds tough (and it can be), but volunteers love the work. No matter what your talent or capabilities, if you want to volunteer, we can find a job for you.
All volunteers must be able to read, write and speak English. Spanish fluency is much appreciated since we have runners from Mexico and South America.
Communications
The Big Bend Amateur Radio Club will be providing most of the repeater network for this event.
Frequencies are subject to change and will be assigned to particpants – check w/ Charlie Angell when you arrive.

Hydration
Big Bend is a desert, and humidity is very low. Stay hydrated and stay healthy. Make sure you have planned your water needs based on what you find you need. Water stops will be spaced properly based on decades of experience, so check that you can carry what you need in between.
Weather
Big Bend weather is famous for being unpredictable. It is usually beautiful, but can be snowing, raining, sleeting, or hot.
In past years in January, it’s been warm (70’s F), cold (20’s F), wet, dry, windy, calm, and of course … rain, hail, sleet & snow.
It’s also been beautiful. There is something about running in the desert after it rains that is just sweet. Rain is rare in the desert.
Trail runners know the basics of hydration, keeping cool, keeping warm, and staying healthy.
Our water/electrolyte stations and medical teams are on hand to keep you safe.
Campers should plan for all of the above.
Injury
If you are injured seriously, we will get you to expert medical care as soon as possible by land or air, depending on the urgency.
Medical Support
Many of our volunteers have received training in emergency medicine, and we will have EMS techs as well as Park Officers.
