Texas Eco Series Rules

Here, you'll find rules, eligibility requirements, scoring notes and other important information for the Texas Trail Running Eco Series.


The Ultra Expeditions Texas Trail Running Eco Series offers runners a chance to experience eight (8) unique races through seven (7) amazing ecoregions.


Eco Challenge – $20*

*Plus tax and registrations fees

The Eco Challenge is a completion challenge where Individuals complete eight (8) Eco Series Races within a two (2) consecutive year timeframe that begins the day you register.

  • The Eco Challenge entry fee is $20 for up to a two (2) consecutive year timeframe, plus tax and registration fees.

  • Eco Challenge competitors must complete eight (8) Eco Series Races within the specified timeframe, to receive the award.

  • A participant is given up to two (2) years from the day they register for the Eco Challenge to complete the challenge. Once a participant completes all eight races, they receive their award and their challenge ends.

  • If a participant reaches the point where they will not be able to complete their challenge within the timeframe, they are notified and removed from the challenge.

  • A person can sign up at any time and their challenge begins the day they register, or within the grace period.

  • Grace period – If an individual registers by Tuesday at 11:59 central following a race start date, his/her registration will be included in that qualifying race.

  • A runner must be officially registered, or within the grace period, for his/her points to count.

  • A runner must complete a race for it to count. This means that a DNF or any other disqualifying factor will result in a "0" score for that race. 

  • All runners are responsible for their own race registration.

  • Virtual races are not included.


Scoring begins after a registered participant completed his/her first qualifying Eco Challenge race. Ultra Expeditions is using a Distance Based Points Formula for The Texas Trail Running Eco Series.

Base Points (Bp) Earned

100m = 100 base points

100k = 62 base points

75k = 46.6 base points

50k = 31 base points

50m = 50 base points

26.2m = 26.2 base points (Marathon)

25k = 15.5 base points

13.1m = 13.1 base points (Half Marathon)

10k = 6.2 base points

5k = 3.1 base points
