Race Day Tracking

Your time and distance for each completed lap will be recorded automatically using a timing chip on the back of your bib. Please do not bend or fold your bib across the chip as this may alter your results. Up-to-date lap totals will be displayed on a TV screen, and will be broadcast to the race website as often as possible. Invite your friends to watch your progress online during your run.

Please make sure to wear your bib at all times as you run the track.  Note that laps will not be recovered by timing if a runner forgets their bib.

Nardini Manor is a century-old country estate situated on five and a half acres of land that includes a maze and a custom-built running path. The property is located in an area of farmland, just South of I-10 in Buckeye, Arizona.

Nardini Manor's owner Rodger Wrublik, a local ultrarunner and instrumental in Aravaipa Running's history, custom built the running path in 2003 for use around the perimeter of the property.

The Aid Station tent will be easily accessible right on the course. The timing tent will be just West of the Aid Station with timing mats that you must cross each loop. You can setup your own tent in front of the manor for no charge.


Top three male and female performances will be awarded in the 24 hr, 12hr, & 6hr races. Masters awards will also be given to the top man and woman in the 24 hour race. (No double dipping).

PLUS! All participants will be eligible for these additional awards:

+Hamster Happy Hour: 'Spirit' award for the happiest hamster on the track--keep the energy & encourage your fellow runners!

+The "Hot Wheels" Award: Fastest lap--open to all participants! Winners (one male and one female) will be announced at the conclusion of the race.

+The Helpful Hamster Award: Open to all volunteers during the event. Awarded at the race director's discretion, the Helpful Hamster is awarded to one volunteer each year for service above and beyond!


Parking will be free and available onsite. Runners will enter the property from Jackrabbit Road through the main gates.  (Please do not drive on the canal service road). Drive slow coming into the main entrance as vehicles cross the race course. Vehicles will be accessible from the race course. Please remember to return to the course where you left it to continue on your loop.

Drop Bags

We will have an area specified for your personal drop bag along the course that will allow for easy and quick access.

Course Marking / Lighting

The course will be easy to follow with cones and flagging to ensure you stay on the correct path. Additionally, at the night, the entire course will be lit so there is no need for a headlamp.


We are excited to offer several camping and tent rental options at the 2021 Hotfoot Hamster.

The camping area opens Saturday morning for camping setup. Tent and cot rentals will be available easily accessible from the course. You may reserve a tent and/or cot when you register for the race.

All rentals will be setup when you arrive. You may check in to receive your tent Saturday morning. Tents will reserved on a first come, first served basis.

Small Tent – $27.33– These are 7 feet by 7 feet, a simple two person camping tent that is tall enough to sit up in, but not to stand. Cot rentals are not available for small tents.

Large Tent – $54.65 – These are 8 feet by 12 feet and are large enough to stand up in (for most people) and may also fit two cot rentals.

Large Tent + 1 Cot – $81.97

Large Tent + 2 Cots – $109.30

Rules and Etiquette

A pre-race meeting will take place 10 minutes before each event. At the start, you will begin circling the trail clockwise. Thereafter, you will change direction every three hours (at 10:00 AM, 1:00 PM, 4:00 PM, 7:00 PM etc).

You may leave the course at any time. If and when you decide to continue, you must return to the course at the exact same place you left it, and complete the lap you were on when you stepped off the track, in the same direction as you were going, regardless of the direction other runners are moving when you return. This ensures that you are credited with the correct number of laps.

There are no DNFs in any of the multi-day runs and no drop-downs allowed. The objective in the multi-day runs is only to go as far as you can (or desire) in the allotted time. Of course, the more time you spend moving forward, the more distance you will accumulate.

If you wish to stop completely before the official end of your race, inform the race director or timing personnel, that you are quitting or leaving early and remember to turn in your chip!

An awards ceremony will follow after the conclusion of the 24, 12 hour and 6 hour events at 7:30 AM Sunday morning.

NO CUTTING THE CURVES. You must STAY OUTSIDE the cones or markers on the curves. The layout of the course at Nardini Manor is such that you would have to be pretty devious to cheat. Nonetheless, if you cut the curves you will be disqualified.

It is your responsibility to know the rules. They exist to provide a good experience for all runners. If you are caught cheating you will be asked to leave and will not be allowed at future Aravaipa Running events.

Course etiquette does not require lone runners to yield the inside lane to runners wanting to pass, regardless of whether the one being passed is running or walking at the time. It is assumed that each participant is there to do his or her best, and has an equal right to pursue personal goals. In a race of this type, it is to be expected that even the best will walk for periods of time, particularly those in the longer races. Always pass others on the outside if they are on the inside lane.

An exception to this policy is the case of two or more persons running or walking together. Persons traveling around the trail in groups should always leave an inside channel open so faster runners do not have to travel far to the outside to get around them.

In all cases, remember to show common courtesy, and that most of us run for the enjoyment and thrill of the experience.


Please respect Nardini Manor and the Wrublik family by disposing of any trash at our aid station or designated receptacles in the recreation area.
