Ask five people in northeast Mesa when hiking season actually begins and you'll get five different answers, most of them tied to a thermometer reading they half remember from last October. Ask someone who actually shows up at Usery Mountain Regional Park every week and they'll give you a date instead: the second Saturday in November, when Aravaipa Running sets up its timing tent at the Trailhead Staging Area and the Pass Mountain Trail Runs take over the park for a day. That race, not the forecast, is the signal locals actually watch. And this year the calendar changed in a way that tells you something new about how the park is being used.
For 2026, Aravaipa is adding a 50 mile distance to the event for the first time, on top of the 5K, 10K, 25K Sonoran Desert Cup and 50K that have anchored the race in past seasons. It's a small addition on paper. In practice it means Usery, a park most Mesa residents think of as a place to log an easy morning loop before work, is now hosting an ultra-distance course that leaves the park entirely, crosses into the Goldfield Mountains, and comes back nearly nine hours later. That's worth understanding if you use this park regularly, because it changes what a normal Saturday there looks like this fall.
The park most people already know
Usery sits on 3,648 acres at the western edge of the Goldfield Mountains, right up against the Tonto National Forest, and it's been the default answer for East Valley hikers and bikers for decades. More than 30 miles of trail fan out from a handful of trailheads, and the mix is wide enough that the same park serves a stroller family and a mountain biker training for a race without either one feeling out of place.
The Wind Cave Trail is the one everyone eventually does. It runs a bit over three miles round trip and climbs toward a natural alcove at roughly 2,840 feet, where water seeping through the rock supports a small hanging garden of rock daisy that has nothing to do with the desert floor below it. The last stretch to the cave itself is a scramble, which is why it shows up in trip reports as both "the best short hike in Mesa" and "harder than the photos make it look."
If you want the opposite experience, the Merkle Trail is a one mile, barrier-free loop around a low hill, built with gentle grades specifically so it works for wheelchairs, strollers, and anyone who wants desert views without a workout attached. Mountain bikers tend to gravitate toward the Blevins, Moon Rock and Meridian network instead, a beginner-friendly loop that weaves between saguaros without much elevation change. And if you're after a real climb, Pass Mountain Trail is the one that gets people out of breath, a genuine summit push that shows up as the final, punishing leg of the ultra races that use this park.
Usery also runs the only Five Star rated archery range in the western United States, according to Maricopa County's own park literature, with six courses and close to a hundred targets. It's the kind of amenity that doesn't show up on a hiking list but explains why the parking lot near the Trailhead Staging Area is busier on weekend mornings than the trail count alone would suggest.
What's actually new this year
The Pass Mountain Trail Runs aren't a new event. What's new is the scale. The 50 mile route, run for the first time in 2026, leaves the park through the southern edge of the Tonto National Forest, crosses the Goldfield Mountains and Bulldog Canyon's sandy washes, links up with the Maricopa Trail, loops through the Hawes Trail System above the Salt River, and finally returns to Usery via Pass Mountain from the opposite direction the shorter races use. Runners hit that final climb with 45 miles already on their legs.
The shorter distances stay closer to home. The 25K and 50K wind through the park's cholla forest and along the Levee Trail before climbing Pass Mountain into the national forest, while the 10K and 5K never leave Usery's boundary at all. Every distance now slots into Aravaipa's Desert Runner Trail Series point system, which divides races into four tiers locals refer to by name: Quail for short distances, Roadrunner for the middle ground, Owl for trail races, and Hawk for the ultra tier the 50 mile now qualifies for.
The race runs the same Saturday as Aravaipa's Punisher Night Trail, a separate looped event that starts once the sun goes down. Finish any distance in both and you get a "Double Down" medal, which is the kind of small detail that tells you this date has become a fixture for the local ultrarunning crowd rather than a one-off.
None of this requires you to run 50 miles to matter. If you're planning a normal Saturday hike or bike ride at Usery on November 14, expect the Trailhead Staging Area to function as race headquarters for most of the day, with courses marked using orange ribbon dotted in black and reflective trail medallions, plus checkerboard flagging on any trail that isn't part of the route so runners don't wander onto it by mistake. Familiar sections like the Levee Trail and the Pass Mountain climb will see steady runner traffic from early morning into the evening.
If you were planning to camp that weekend, book early. The Buckhorn Family Campground's 73 individual sites, each set up for tents or RVs up to 45 feet with water and electric hookups, get reserved by race participants and their crews well before race day, and the county books those sites online through its own reservation system rather than through the event itself.
The nights are opening back up too
The same seasonal shift that brings the race calendar back also brings back the park's after-dark programming. Maricopa County contracts with Stargazing For Everyone, LLC to run telescope-equipped stargazing nights across its park system, Usery included, and the county provides the equipment. You bring your own chairs and snacks, and the one hard rule is no pets, which is worth knowing if you've gotten used to Usery's more relaxed daytime policy on dogs along the main trails.
Pair a stargazing night with a Wind Cave sunrise hike the next morning and you've got the two bookends of what a fall weekend at this park actually looks like for the people who use it regularly, race day or not.
Why this matters if you live here
None of this is a reason to move to northeast Mesa. It's a reason to pay attention to a park you might already take for granted. The day-use fee is still $7 per vehicle, the trailheads are the same ones you've used for years, and the desert doesn't look any different in November than it did in July. What's changed is the scale of what this park is willing to host, and that's a fair proxy for how much use it's getting overall. A park doesn't add a 50 mile ultra distance because attendance is flat.
If you're the kind of Mesa resident who plans a season around when Usery's trails stop feeling like a furnace, the county's own park page and Aravaipa's race site are the two places worth bookmarking before the weather actually turns.
If you ever find yourself wondering what else has shifted in this corner of Mesa, from what's opening downtown to how the surrounding neighborhoods are actually trading, that's the kind of question Jesse Lowery fields regularly from people who grew up here and still keep close track of it.
