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.
Our 100K is a qualifying race for the 2025 Western States Endurance Run race
Our 100K is now a Western States qualifying race!!! This event has grown tremendously and shown a level of execution that puts us on a national level. We are now one of only 18 100K qualifiers in the United States for the 2025 Western States Endurance Run race.
If you complete the 100K distance in under 22 hours, you earn your qualifier for the next year’s lottery.
We focus a lot on inclusion and diversity initiatives, so this will also add more diversity into the lottery and ultimately the start line of the race!
Even 100 Milers will get a 100K finish!
Because the 100 Miler's last 5 mile loop is at the end of the race, both 100K and 100 milers will come through the finish line area at the 100K mark doing the exact same course. We record everyone's 100K split, regardless of distance registered for, as an actual 100K finish because you completed 100K. 100 milers who drop out of the race before 100K will show as a DNF. 100 milers who drop out of the race before their 100 mile finish but after 100K will not show a DNF because of the 100K recorded finish, and they will receive a 100K buckle. All 100 milers who finish out the full 100 mile distance will get a 100 mile buckle instead of a 100K buckle but will also have a recorded 100K finish!
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: https://trailmixfund.org/
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!
