Cross Timbers Trail Run

5 Mile / Half Marathon / Marathon / 50K Ultramarathon

February 22, 2020


We need volunteers! Getting participants to the finish line of an ultramarathon is a COMMUNITY effort. And we want to continue to make this the great race that Teresa Estrada did for the last 11 years and that the race directors before her established.

It takes a lot of volunteer shifts to make this event successful. We are thankful for our volunteers. Please look over the list below and then email us to volunteer!

Volunteer Shifts

In order to produce the most successful race at Cross Timbers, we embrace that our volunteers make up a huge part of producing a great race for the runners. We would greatly appreciate your time & efforts in any of the following positions:

  • Parking (5 - 8 AM) - 2 people (great for a family or friend who will be ultimately waiting for you at the finish!)
  • Aid Stations and Start/Finish help: 6 am to 11 am, 11 am to 4 pm, or both! (We love people who can help all day to aid station shutdown!) 12 people per time shift needed! If you have specific, partial hours you are able to help, please let us know. If you have a specific place you want to volunteer (locations are: Cedar Bayou, Rock Creek Resort, Paw Paw Point, Finish Line) or with a specific friend, let us know that too!
  • Sweeper (10 AM - 3:30 PM) - 2 people. Follows behind the last runner to keep everyone safe (so we know the trail is cleared) and picks up flagging along the way. Needs to be able to complete 13 miles. We can split this among multiple people easily if needed, so if you can't do 13 miles but want to do this, still let me know!

How to Volunteer

When you email , please state clearly

  1. what shifts you can take. If you can work more than one shift, tell us because that would be awesome. If you can only do a partial shift in your schedule, we're still thankful for the help and just let us know any limitations.
  2. any friends you want to volunteer alongside. If you have friends also planning to volunteer, please let me know who you want to be paired up with, and I will do my best to not split friends up when assigning volunteers to the aid stations!
  3. Let us know if you have medical training. We like to have a nice spread of people who are CPR-certified and could help bandage basic wounds and such out there across our aid stations.
