Hotfoot Hamster puts you on a flat, USATF-certified 500-meter gravel loop at the historic Nardini Manor and gives you 24, 12, or 6 hours to cover as much ground as you can. There are no mountains here and no finish line pulling you in, just the loop and the clock. I will walk you through the format first, then give you a pacing and fueling plan built for a timed loop event, with free calculators along the way to dial in your own numbers.
These facts come from the official Aravaipa race page. Check the current date, start times, and aid in the race-day details before you commit. Race logistics change year to year.
Hotfoot Hamster runs on a USATF-certified, flat, crushed-gravel 500-meter loop winding around the grounds of the century-old Nardini Manor. There is zero elevation gain per lap, so the challenge is not finding your way or climbing anything, it is rhythm and repetition over many hours.
A totally flat course lets you run efficient, even splits with nothing to break up your stride. That same flatness means the same muscles fire the same way lap after lap with no downhill or uphill to vary the load, which is why a lot of runners are surprised that a flat loop leaves their feet and legs more beat up than a hilly trail race of similar duration.
You can set up your own tent, chairs, and supplies right on course at no charge, turning every lap into a chance to grab exactly what you need. Use this. Stage food, layers, and fresh socks trackside and let the loop bring you back to them on a schedule instead of carrying everything.
The 24-hour and 12-hour events start once, at 7:00 AM. The 6-hour option offers four different start windows (morning, day, night, and a 1:00 AM "insomniac" start), so you can pick the conditions and time of day that fit your goals, whether that means racing in daylight or testing yourself through the dark.
A flat, timed loop rewards restraint and consistency more than almost any other race format. The runner who slows the least covers the most distance.
A flat, fast course on fresh legs feels deceptively effortless in the opening hour, and that is exactly the trap. Treat the first stretch as controlled, easy aerobic effort well under what feels comfortable, since going out too fast on a flat loop borrows directly from the miles you need late in a 12 or 24 hour effort.
Set a target distance and pace backward from it into a per-lap or per-hour number, then use the loop as a constant checkpoint. Every lap tells you whether your effort is sustainable or quietly running you into the ground, which matters far more here than any single split.

A flat, timed loop is one of the most fuelable formats in ultrarunning, since real food, your own supplies, and the main aid tent all come back around every lap.
Aim for roughly 60 to 90 grams of carbohydrate an hour once you are settled in, leaning on both the on-course aid tent and your own trackside supplies. Mix gels and drink mix with real food to keep your appetite alive over many hours rather than relying on sweet-only fueling that tends to quit on you late.
Buckeye can run warm even in late May, especially during a daytime 7:00 AM or 1:00 PM start. Sodium in the 400 to 700 mg per liter range covers most runners, and grabbing ice at the aid tent during the warmer hours is a simple, effective habit. Weigh yourself before and after a similar-length training effort to learn your real sweat rate.

Hotfoot Hamster is hard in the way every fixed-time race is hard: there is no finish line pulling you forward, just a flat, fast 500-meter USATF-certified loop and a clock counting down 24, 12, or 6 hours. The course itself is as forgiving as ultrarunning terrain gets, flat crushed gravel with zero gain per loop, so the difficulty is entirely about repetition, fueling, and how long you can keep circling. The all-time course records, 149.13 miles for men and 130.49 miles for women in 24 hours, show what is possible when pacing and fueling both hold up for a full day.
Effectively none. The course is a flat, USATF-certified 500-meter crushed-gravel loop around the grounds of the historic Nardini Manor, with zero feet of gain per lap. That flatness is the whole point: it lets you run efficient, even splits without a single climb or descent to break up the rhythm, though many runners find that repetitive flat pounding leaves feet and legs more beat up than a hillier course would.
It is a classic fixed-time ultra: choose 24, 12, or 6 hours, then cover as much distance as you can on the 500-meter loop before the clock runs out. Aravaipa offers multiple start times for the 6-hour option (morning, day, night, and an "insomniac" 1:00 AM start) so runners can pick the window that suits them, while the 24-hour and 12-hour events start once, at 7:00 AM.
Go out easier than feels necessary. In a fixed-time event the runner who slows the least over many hours covers the most distance, not the one who starts fastest. Treat the opening hours as controlled aerobic effort, keep your loop splits honest and consistent, and plan short, purposeful aid stops rather than long sit-downs that get harder and harder to leave as fatigue builds.
The main aid tent sits directly on course with vegan, vegetarian, and gluten-sensitive options available on request, plus a nearby timing tent with mats you cross every loop. You can set up your own tent or chairs trackside at no charge. The course is fairly well lit at night but has some dark stretches, so Aravaipa strongly recommends a headlamp and extra batteries even though full darkness is not the norm here.
Yes, and Aravaipa markets it that way: a flat, fast, USATF-certified loop is one of the most approachable formats in the sport for a first ultra distance or a personal best attempt. Choosing the 6-hour option lets a newer runner experience the fixed-time format, frequent aid access, and pacing discipline it teaches, without committing to a full day or night on course.
