Dinosaur Valley Endurance Run

Aid Stations

Aid Station Locations and Supplies

Aid Station Locations

There are two physical aid station locations which are accessed multiple times during the race depending on the race distance. The 100 miler involves visiting these aid stations a total of 28 times!

FENCE LINE is an aid station you hit outbound and inbound in the longer 10.5-mile loop so make sure you know which way you're headed or ask the volunteers if you don't know. 5 milers only hit Fence Line once outbound.

CEDAR BRAKE is accessed at the start/finish of each loop. It is two-way traffic from Cedar Brake to Fence Line aid station.

We are Cupless

We're a firm believer in the Leave No Trace principles of trail etiquette, so this will be a Cup-Free Event to eliminate the chance of litter. There will be no paper cups for cold beverages at this event. Everyone must carry some sort of hydration system with them, whether it's a handheld water bottle, a waist fuel belt, or a hydration pack. For other drink needs besides water at the aid stations, we recommend the Ultraspire C2 collapsible reusable cup or the Hydrapouch.

Aid Station Supplies

Water: You are expected to carry a hydration solution that will allow you to do a full loop (whether that’s 5 miles or 10.5 miles for your race distance). Water will be served at all of the aid stations.

Other Beverages: Multiple brands of soda as well as pickle juice to drink!

Electrolyte Drink: The electrolyte drink on the course will be Tailwind Nutrition.

Food: Most of the usual aid station fare at a minimum. Cookies, candy, peanut butter and jelly sandwiches, chips, pretzels, and more. Energy gels are such an individual item that we will not be providing - bring your own favorite if you want to use these as fuel.

Beginning at 5 pm on Saturday through 3 pm Sunday, hot foods and liquids will be available at the aid stations. A rotating assortment of a couple options will be available as volunteers cook things up. This food is not available to 25K and 5 milers.

NOTE: Not all foods will be vegetarian friendly, and those with special needs (gluten-free or vegan, for example) and those who are super duper picky should plan to bring their own nutrition. Those with severe food allergies or conditions (like a nut allergy or celiac disease) need to be aware that we can not guarantee against cross-contamination. We can not guarantee that certain foods are Halal-certified or Kosher.

Other Supplies:

We will have band-aids for minor cuts.
All-in-one “pack it in, pack it out” Menstrual Kits: Menstruation is an additional complicating variable for some of our participants. We want to make sure our participants are served while also maintaining a protection of the “leave no trace” environmental trail running principles we hold dear. Therefore, all aid stations at this race and all The Active Joe trail races will have multiple menstrual kits that contain a couple wet wipes, an ultra-thin menstrual pad, and a tampon in a Ziploc bag. As tampons do not degrade well in the environment, this kit helps our participants remember to “Pack it in, pack it out” by disposing of used tampons with the wet wipe in the Ziploc bag and saving it on their person or in their pack until they can throw it away in the trash at the next aid station.
Aid stations will not provide Advil, Aspirin, Motrin, or any other pain relievers.
Aid stations will not have blister kits. If you are concerned about blisters, carry what you will need in your pack or make sure it's in the drop bag at each location you might need to use it. Adjacent to Cedar Brake aid station at the 2024 event, we will have a Foot Care tent in Valley Village (See section in Valley Village about administrative tents available).

CHECK-IN/OUT & DROPPING

At the CEDAR BRAKE Aid Station, if you go to the crewing area, Valley Village, you can just head out on the course and you don’t have to check out with the aid station, re-cross the mats, or verbally check out by yelling your number.

At FENCELINE aid station, participants are expected to check OUT when leaving an aid station. If you are bib 482, when you arrive, yell "482 IN." When you leave, you or your pacer (for 100 milers) should yell "482 OUT". We have split mats but if anything goes wrong, volunteers need this to be able to manually record you.

If you decide to drop out of the race, you must please let the aid station captain know and make sure they note it on their clipboard. We don't want you to leave with your crew and then we're calling you or your emergency contact a couple hours later looking for you, or searching the expanse of the trail system for you!

Volunteers will work to monitor every participant's ingress to and egress from the aid stations. We reserve the right to disqualify anyone whose times between any check-in or check-out do not grossly align with the paces expected based on their moving times the rest of the race and their racing history.

100 Milers ONLY can drop down midrace to the 100K and take that finish and not have a 100 Mile DNF, but you must check in at the Headquarters at the finish line so it is properly recorded and you receive your finisher items.
