Fossil Valley


** Texas Trail Running Championship Series – Spring Awards Ceremony Info


12/9/16 IMPORTANT:

I am sorry to announce all EBA races have been cancelled for 2017. Full refunds have been issued for any registered runners.

If you like more of a story, you can read that here.


An adventure-filled summer sun-free run at the Cedar Ridge Preserve in Dallas, Texas that includes a unique community format that allows you to run as much as you want and rest when you need to.

We are going nocturnal! Enjoy and maybe experience for the first time, a night running adventure. Watch headlamps dance through the hills. Stop, turn off your lights and look at the stars above.


Whether you are running 8 minutes/miles or 20 minutes/miles, everyone in your race will finish together and celebrate together.

With each loop being a fun and adventure-packed 2.69 miles, you will share tread time with runners of all paces throughout the race. Also with this modest loop length, there will often be runners nearby offering encouragement to one another regardless of your pace or the time in the race.

Choose your adventure!

3 hours, 6 hours, or 9 hours of trail running community goodness.

How many miles you run is up to you!

Pics taken during the winter months. Expect much more green come July!

What the Tribe is Saying about Fossil Valley…

Thank you volunteers and organizers. Great race last night at Cedar Ridge Preserve. The 2.68 mile loop was challenging and the 10PM start time was a perfect training tool to acclimate to running all night. Well done Dave and Company. I want to do this again!

Fossil Valley

I was so very nervous going into this race but I finished it feeling pretty amazing! Once again, you have put on a great race - you know how to bring out the best support and crew to make each event an adventure!

Fossil Valley

Thank you so much for putting on a top-notch event this weekend! I'll be definitely bringing some folks with me from Houston next year, the HTRex crew will be well-represented if I have anything to do with it. 🙂

Yeah Earth! 🙂

Cedar Ridge Preserve has been gracious in allowing runners to set up basic tents on property for the duration of the event (Saturday night through Sunday morning). We will likely have some space near the start/finish area as well as a little roomier area a short walk from the start/finish area (just past the maintenance building for those familiar with the area). Tents ONLY due to the space availability. No showers.

Cedar Hill State Park is also just a couple miles away.

There are a variety of hotels within 3-5 miles of race site.

All runners will receive a cool finisher’s gift and unique medal.

Fast Feet gift awards for 3 Hour, 6 Hour, and 9 Hour race:

  • Top 3 male and female finishers
  • Top male and female in age group 29-and-under
  • Top male and female in age group 30-39
  • Top male and female in age group 40-49
  • Top male and female in age group 50-59
  • Top male and female in age group 60+

9 Hour Relay (3 Person) race award:

  • Top team in Overall (the 9 Hour Relay will be one division regardless of group gender mix.)

*For this format awards are based off of number of completed loops and then accumulative time if necessary. For example: You and another person finish with the most laps in your age group with 5 laps. You (Cool dude) completed the 5 laps in 2:58:02 and the other person (Other Cool dude) completed the 5 laps in 3:01:02. You (Cool dude) will receive the award because you ran the loops in a faster accumulative time. Make sense?!?

**No stacking of awards. Overall awards assigned first. Then age group awards (except for 9 Hour Relay division where there are no age group awards). The gift award would roll down to the next person.
