Dinosaur Valley Endurance Run
2026 Evolutions - No Extinctions Happening Here!
How do you keep evolving to provide the best event you can? Unlike our poor dino friends, extinction is not in our vocabulary! Based on your feedback in last year's post-race surveys, we’re revising a few aspects, especially logistics and the event's environmental footprint, to ensure the experience is smoother, more sustainable, and more enjoyable for everyone.
This page is a one-stop shop to find the changes and make sure you're up to date, especially if you're a returning athlete.
Changes for 2026
-
Shuttles were by far the least fun part of race weekend for both us as race producers and the athletes as participants. We have talked to the State Park, and we will be working with them to create a safe and workable solution for parking that will remove the need for shuttles while still utilizing the land in the most environmentally conscious way that we can.
-
Fewer restrictions on allowable crew supplies. Without shuttles, we will be allowing more items to be brought onsite, but if you bring it to the race, remember that tired hands and legs have to take it down and haul it out.
-
Crew areas will be changing. We had a lot of success with professionally erected tents for crewing. We will add to those areas to make them a more enhanced amenity while creating an area for personal pop-up canopy tents that athletes want to haul in and out themselves. More details on that later.
-
Course records updated. We had several course records reset. See them here...
-
Shorter distances races on Saturday morning (50K, 25K, 5M) will start at 8 am instead of 9 am. See the Schedule page...
-
New names for the Saturday morning and Sunday morning races, giving them their own identity. Each day is its own standalone events, and finish times from each day won't be combined. Each event will have its own awards. More info on the Race Information page...
-
New 5 mile added on Saturday evening. With an 8 pm start, races get a chance to try out nighttime racing. Hiking is encouraged! More info on the Race Information page...
-
A special Mesozoic Maniac reward for those doing the 3 5-mile races offered during the weekend. You're "in your Mesozoic era" with these 3 races bearing the names of the time periods of that era: the Triassic 5 Mile on Saturday at 8 am, the Jurassic 5 Mile on Saturday at 8 pm, and the Cretaceous 5 Mile on Sunday at 8 am. Complete all 3 and receive a special reward that will be revealed closer to the race. This is perfect for crew members who want to push themselves and want to see what the course is like at night! More info on the Race Information page...
-
There will be no 50K race start offered on Sunday of race weekend. A lot of racers found hitting the cutoffs on that day to be difficult. With a Saturday start and 100 mile runners running until Sunday afternoon, it takes away cutoff anxiety! The 50K will now ONLY start on Saturday at 8 am. See the Schedule page...
-
New change to how close to the race we will allow distance changes. We will not limit distance change requests to as long as we have room available (must email to check) AND before November 14. This allows us to focus our small team on setting up the race site and lower the amount of computer work and redoing race packets!
-
We will introduce a new buckle design in 2026. We have no many returning runners year after year that we want to be able to offer a new buckle design for them. More details on this later!
