Welcome to the 8th year of our event at the beautiful Dinosaur Valley State Park in Glen Rose, Texas. The Active Joe brought North Texas its first 100 miler, and we continue to grow every year! We offer 5 distances so there's a challenge for every interest level.

In all these distances, you’ll be among other amazing athletes challenging themselves. There are lots of gradual up and downhills that add up, and a mix of terrain between soft dirt, rocks, and roots. Some parts are technical while other parts are super runnable. This is a pretty hilly 100 miler by Texas standards, and the terrain can trip you up as you fatigue. Use that first loop through the course to settle into a pace for the race and not go out too fast.

Operation Get-A-Local-Western-States-Qualifier

We're on a mission to grow the 100 miler after several years of solid race execution and consistent growth so that North Texas can finally have a Western States qualifier available to us locally! In 2022, we had 235% of the 2021 finisher count in the 100 mile and 100K, and we're on the path to getting to our goal! Registration for the 100 miler and 100K will open first and at an entry fee of $85 through 12/31! More details in the "News" section of The Active Joe's website
All other distances will open 1/2.

50K, 25K, and 5 Mile Races Saturday AND Sunday

The 50K, 25K, and 5 Mile entrants have the ultimate in flexibility - now they can choose for themselves whether they run the race on Saturday or Sunday. All 3 distances will start at 8 am Saturday and 8 am Sunday. You can decide up until the last minute, and you don't have to tell me ahead of time which day you will run. Our timing system will start recording you when you start either day!

Please only pick up your packet on the day you are running so that you don't accidentally have your timing chip read by the timing system near the start line. Results will be combined after both days of races, and awards mailed out.

For 50Kers doing Sunday, please keep an eye on cutoffs which you must still meet.

For those in the 100 mile and 100K, this means the race course will never get too lonely. I feel it will help keep the energy up through the whole weekend!

We are part of the Trail Mix Fund!

Do you want to race but can’t afford the entry fee? Are you a part of the BIPOC or LGBTQ+ community? Apply to the Trail Mix Fund to have your registration fee waived. You can learn more on the website:

In an effort to improve the diversity in trail racing and remove a potential barrier for the under-served and under-represented, we've partnered up with the Trail Mix Fund, a 501(3)c non-profit. While we all like to think this sport is accessible – “you just need a pair of shoes” – that just isn’t always the case. The Trail Mix Fund is available to anyone wanting to run a race who could use some assistance in paying for it and for those from the BIPOC & LGBTQ+ communities. During registration, we are accepting donations to their organization. All donations made here go directly to the Trail Mix Fund, not to this race. Please consider helping this organization by donating!
