Frequently Asked Questions

What does crepuscular mean?

You may know that nocturnal animals are those that are active at night, such as bats. Humans are diurnal- that is we are active during the daytime. Some animals are neither diurnal nor nocturnal. These animals are crepuscular,or most active during the twilight hours of the day. Deer are a great example – Consider that you are most likely to see deer around dawn and dusk!

What event options are there?


  • 5k
  • 10k
  • 100k Ultra


  • 30 Mile
  • 3 Mile

What activities count?

For the 5k, 10k, and 100k Ultra, any physical activity besides cycling, including running, walking, or using a wheelchair, will count towards the distance. If you wish to bike, use a handcycle, or other cycling equiipment please register for the 3 Mile or 30 Mile Cycle Options.

Will age brackets be considered?

Yes. Participants will be sorted into the following age brackets:

  • 0-11
  • 12 -17
  • 18 – 35
  • 35 – 50
  • 50-65
  • 65+

When do I need to complete the distance by?

For all options except the 100k Ultra, participants will complete their distances during the last week of October – the 25th to 31st. Those who register for the 100k Ultra will have the entire month of October – the 1st to 31st.

How long will registration be open?

Registration will be open until October 30th for all events. However registering after the start date for the event will result in less time to complete it. For example, someone who registered for the 100k Ultra on October 15th would have two fewer weeks to register than someone who registered before the 1st.

How do I submit my time?

There will be an email sent to you with a result submission form where you can enter your time. To be considered for placing, you must also submit screenshots of your activity tracker. All times must be submitted by November 2nd.

Do I need to do it all at once?

You do not have to complete the entire distance in one time. If you choose to split it up, and wish to be considered for placing, be sure to take screenshots of each session. There will be separate brackets for those who complete their whole event at once and those who complete their events in multiple sessions.

Where can I complete this event?

Anywhere! You can participate from your favorite trail, your neighborhood, or even on your treadmill! Just be sure to time yourself so that you can submit your results.

What will be included in the Night Hike PDF?

One of our most popular evening programs during Outdoor Education is our Night Hike. Students learn about how different animals survive in the dark through a series of engaging activities. The Night Hike PDF contains all the information you need to facilitate ten of these activities at home. Many of these activities require only a few, common materials, and can be done within a single family or household. While we recommend doing them outside if possible, the majority of these activities can be completed inside your home!

Are there any rules for the Costume Contest?

We ask that any costume contest submission be appropriate for our audience. As a non profit organization serving youth, Pathfinder Ranch will not post photos that contain mature themes, political references, or inappropriate content as determined by Pathfinder Ranch.

Is registration refundable?

Once you have submitted registration, this event is not refundable.
