We absolutely love our 4-legged participants! To ensure a fun and safe day for all runners, please observe a few rules:

• Socialization & Comfort: The event environment is high-energy, featuring large crowds, other dogs, and loud noises. Your dog must be comfortable in this setting. For the safety and stress levels of all involved, we reserve the right to ask you to remove your dog from the course if they appear overwhelmed or reactive.
• Leash Safety: Please be sure to lock your retractable leash to a short lead (non-retractable is preferred) and keep your leash as short as practicable at all times. You must maintain full control of your dog throughout the event.
• Start Line Etiquette: Please line up behind those runners who are "in it to win it" at the start.
• On-Course Etiquette: We hope this goes without saying, but you must follow all municipal laws regarding keeping dogs leashed. Additionally, you must immediately pick up any poop, whether your dog relieves itself on or off the trail.
• Hydration & Treats: Every aid station and the finish line aid tent are equipped with dog water bowls. Plus, we'll have dog treats waiting for your furry friends at the gear check tent!

Oh, and be ready for our staff to love on them a bit... or a lot!

Yes, however, for your safety, please be sure to keep the volume at a level where you can still hear announcements, course instructions, and other users of the trails.

Absolutely, all are welcome to participate using a stroller or wheelchair!

We just ask that you follow a couple of guidelines for everyone's safety and smooth course flow:

• Please start at the back of the pack to prevent blocking the course for your fellow athletes.
• Make sure to look at the event page for trail surface materials to ensure they are compatible with your stroller or wheelchair, especially those that have smaller wheels.

We have access to the indoor, heated stadium restrooms at NAAC, plus multiple units on-course, so you won't wait in long lines.

You betcha! Beginners and veterans alike are welcome at all All-Out events. Please feel free to participate as competitively as you feel comfortable—we are here for you! To support every athlete, we proudly offer a no time limit on any distance as long as you are actively participating.

Absolutely, all are welcome! Please get in touch with us directly and as far in advance as possible so we can make any necessary arrangements to support athlete needs.

We are also pleased to offer free registration to any athlete who is assisting a mobility, hearing or visually impaired participant.

Yes! Please ensure your race bib is worn on your outermost layer, is horizontal, and is always clearly visible from the front.

Proper bib placement is critical for several reasons:

• Safety: It helps our staff quickly identify you in case of an emergency and our course marshals properly direct you on course, and our aid station volunteers know that they can serve you.
• Accurate Timing: The timing chip is on the back of the bib—if it's not on the outermost layer, we might not get a time for you!
• Photos: It helps our photo indexing identify you later so you can find and download all your free race photos.

We at All-Out are proud to include competitive runners, joggers, walkers, canine companions, wheelchairs, and strollers! We ask that all participants show respect for fellow athletes and the public you are sharing the trail with by following basic trail etiquette and staff direction for start line positioning on race day.

If you observe poor etiquette or sportsmanship, even if you are not a participant in the event, please notify us in person or via email.

Allegations of cheating or shortcutting the course will be investigated and, if found to be accurate, all awards will be retracted and must be returned and cheating will result in a ban from all AMP events for 1 year. Egregious poor etiquette observed on the course or if we receive reports of or observe unsportsmanlike conduct on the course, before, or after the event, we will issue a ban from all AMP events for 1 year, or a lifetime ban, depending on the seriousness of the offense. 

We have limited 4-ounce cups of water at the meal tent pre-race.

You betcha! We specifically choose our venues so there is ample, free parking for our athletes.

However, please take note of two key details:

• Snow Plan: If it has snowed, please be aware that we cannot plow the event parking lot, so be prepared to park in snow
• Lot Closure: The gates to the venue lot close promptly at 1:00 PM when the last athlete finishes. You will not be able to access your vehicle if it is left at the venue after this time.

Take a look at our course details page for details on the parking location.

YES. We strongly encourage all athletes to arrive with plenty of time! First, make sure to check the event schedule for when packet pick-up/registration closes for your distance, as we must close these in advance to prepare for timing. Second, for safety and accurate course management, we do not allow athletes to start after 5 minutes past the official start time. We need to know when and where all supported athletes are on the course. If you arrive after these cutoffs, we will still provide you with your race swag, but you will not be allowed to run the course with a bib as a supported athlete.

While permits to use the parks and trails are set to end at a certain point, we do our very best to allow plenty of time. We will always have a course sweep so we can support those who might fall a bit behind the pack, and we will not cut you off for the 5K, 10K, or half marathon distances if you are actively participating in the event. We find most all half marathon athletes finish within four hours, even those who choose to walk the entire distance.

We're proud to offer a gear check service for your convenience! If you choose to drop a layer after starting the race, all clothing dropped at your first pass of an aid station will be whisked back to the gear check tent before you finish. While you may drop items at any other aid station along the course, please be aware that those items might not be brought back to the venue until the end of the event.

Make sure you keep your bib to collect any checked gear, we confirm for your safety!

If you leave the venue before collecting your lost & found items or checked gear, we will hold it for 3 days after the event.

Please email us to arrange one of the following options:

• Pick up your gear.
• Have it shipped to you (a packaging and handling fee will apply).
• Have us bring it to your next All-Out event.

To maintain a healthy environment for all athletes, there will be no smoking (including vaping) or use of tobacco products permitted on the course or within the venue. If you are reported to be or observed using tobacco, you will be disqualified from the event.

Rest assured, this event offers the distance you trained for! We use a dual-GPS system and the shortest-path method to precisely measure our courses and determine turnaround locations. We measure every course multiple times on the ground, ensuring accuracy. While digital apps like Strava estimate distances based on digitized trail routes, which may show minor differences, you can have confidence that our course is accurately measured to the expected distance.

Check out your distance's start time on our Schedule page. It is very important that you start within 5 minutes of your start time for course operations and safety.

The Start and Finish Line are in the exact same place: at the east end of the venue, through the green tent and directly under the big arch.

We love that you're an alumnus and have been to our events before! However, somewhere around half of all the people in the starting chute are joining us for the very first time. Because of this, we provide all athlete details in the get ready email sent out on Monday before the race (with a copy on our website). Then we feel it's important to make sure we announce the most important safety and logistical details at the start line. (But don't worry—we're glad we're not reading all the details straight from the website either!)

You’re right—using bigger markers would certainly be easier to see! However, can you imagine what our beautiful Colorado trails would look like if all races did that? All-Out Multicourse has a very strict "Leave No Trace" policy. To adhere to this, we use gaffer’s tape that can be easily removed by our course sweep following the last athlete, ensuring our impact on the environment is minimal.

No need to carry extra weight! Course aid stations are an average of just 1.4 miles apart and include water and electrolytes in 4-ounce cupfuls, and energy gels. They also have Superganix plant-based balm and first aid kits. Check out the course details page for the location of the aid stations for your distance.

We pride ourselves on having some of the best-marked courses in the area! We use ground markings of bright green gaffers tape, directional signs on green sign boards, and volunteer course marshals to guide you, but it is ultimately the athlete's responsibility to ensure they follow the course.

To help you prepare:

• Maps Available: Downloadable and interactive maps are available on the course detail page.
• On Display: A large course map will also be posted on display at packet pick-up for review.

To ensure the safest and most enjoyable experience during colder months, here is our policy for winter events:

• Later Starts: Events start at 9:00 AM to allow ambient temperatures to rise.
• Plowing Policy: Events are held on public trails, and All-Out does not control the plowing of the trails or venue. Events will proceed regardless of the snow or ice condition of the trail or venue.
• Cancellation/Shortening:
• • Events will not be canceled due to winter weather conditions unless a CDOT advisory is in effect that limits road travel to emergency and essential reasons.
  • If incoming weather is predicted to cause such an advisory during the event, the event may be shortened to end prior to the advisory effective time.
• Cold Temperature: Events will be held regardless of the prevailing or predicted temperature unless a cold weather advisory or warning is in effect.
• Athlete Flexibility: Any athlete may shorten their distance before or during the event, if they notify the registration or timing staff before starting or immediately after finishing. They may also switch to a virtual participation any time before the start of their event.
• Updates: In the case of existing or predicted winter weather, trail and venue condition updates will be provided on the event website and social media the day before the event so that athletes can prepare accordingly.

We take athlete safety seriously when dealing with severe and unpredictable weather:

• Shortening the Event: If lightning, tornados, hail, or similar severe weather is predicted at a likely chance or higher, the event may be shortened to end prior to the advisory effective time.
• Lightning Protocol: If lightning is detected within a 6-mile radius of the event, the race will be paused. If the lightning causes a delay longer than 1 hour, the course may be shortened to finish within our permitted time frame.
• Flooding: In the case of flooding on the course, the course may be altered or shortened to avoid flooded areas.
• Rain or Shine: Events will be held rain or shine. Any athlete may shorten their distance before or during the event if they notify the registration or timing staff before starting or immediately after finishing.

If any other dangerous condition is known on or adjacent to the course (such as a bear sighting or an armed individual), the event will be altered, postponed, or canceled. The specific action taken will depend on the expected timeframe of the dangerous condition.
