NIKE ACG SWEEPS CHONGLI 168 WOMEN'S 70K IN 5:40:13

Five hours, forty minutes, thirteen seconds. That is what it took Shea Aquilano to cover 57.86 kilometers of Hebei mountain trail in the rain, the mud, and eventually the dark, and it was still forty seven seconds quicker than the woman right behind her. Ren Ti crossed in 5:41:00. Together the two turned the Chongli Ultra-Trail 168 women's 70k into a Nike ACG podium sweep, and the brand's own caption said it plainly: the Racing Dept had gone one and two. A race result is not a marketing claim. It is the one thing a trail brand cannot fake.

5:40:13 to 5:41:00. Forty Seven Seconds Decided It.

Aquilano and Ti finished first and second in the women's 70k at the Chongli Ultra-Trail 168 on July 12, 2026, a course measured at 57.86 kilometers with 2,206 meters of elevation gain, roughly the height of seven Empire State Buildings stacked on a single loop. Conditions turned during the night section: rain slicked the descents, mud swallowed footing on the switchbacks, and both women finished the final kilometers by headlamp. A forty seven second gap after nearly six hours of climbing and descending in the dark is not a comfortable margin. It is a photo finish stretched across a mountain range.

Shea Aquilano Already Broke In the Shoes at Western States

Aquilano is a member of Nike ACG's All Conditions Racing Department, and Chongli was reportedly her first international win. She is not new to racing in the brand's gear under pressure. At the 2025 Western States Endurance Run, she laced into the ACG Ultrafly about two weeks before the start and said the shoe gave her "a good blend of responsiveness and cushioning," with breathability and drainage that kept her legs from getting beaten up over a long course. That is not a sponsor's talking point. That is an athlete describing a tool that worked when it mattered, twice, on two different continents.

Chongli Hosted Olympic Snowboarders Four Years Before It Hosted This

Chongli sits inside Zhangjiakou, in China's Hebei province, on the same slopes that carried freestyle skiing and snowboard events during the 2022 Winter Olympics. Four summers later, the same terrain is hosting a 70 kilometer trail race instead of a halfpipe final, which says something about how fast the region rebuilt itself around endurance sport once the Olympic infrastructure was already in the ground. The Chongli Ultra-Trail 168 is not a fringe local race. It draws an international UTMB circuit field, and Nike ACG's name now sits on the event itself, not just on the runners in it.

260 Dollars Buys a Carbon Plate Split Down the Middle

The ACG Ultrafly, the racing shoe built for exactly this kind of day, retails at 260 dollars. It pairs a dual density ZoomX midsole with a carbon plate cut roughly seven eighths of the way through the shoe and split down the center, letting each half of the forefoot flex independently over uneven rock instead of pitching the foot sideways. Nike put the shoe through 13 rounds of testing across more than 30,000 miles before it shipped. A Vibram MegaGrip Litebase outsole with 3 millimeter lugs handles the traction, a full length ZoomX sockliner is a first for a Nike trail shoe, and the last is cut wider through the toe box, useful when feet swell seven hours into a race run partly in standing water. At 260 dollars, that is not an impulse buy. It is priced like the marathon supershoes it is descended from.

The Ultrafly Runs the Same Playbook as the Vaporfly

The ACG Ultrafly shares its ZoomX foam and split carbon plate architecture with Nike's Vaporfly and Alphafly, the road racers that turned sneaker culture into carbon plate collectors for the last decade. That same formula has now been built again for mud instead of pavement, and the Racing Dept, a 22 athlete roster spanning eight countries, is the field test. The same weekend Aquilano and Ti took the top two spots in the 70k, Racing Dept runners also placed across the men's 30k and women's 50k at Chongli, a sweep that extends well past one race and into how the brand is building proof before it builds hype. Nike ACG has run seven campaigns in five months, staged a runner against a Porsche in Montana with its 22 athlete roster, and put its name directly on a Chinese ultramarathon. Chongli is the version of that strategy with no stunt attached, just a stopwatch.

The verdict is in the numbers, not the campaign. Aquilano's 5:40:13 beat Ti's 5:41:00 by 47 seconds across 57.86 rain soaked kilometers, and the shoe on both women's feet costs 260 dollars because Nike spent 30,000 test miles making sure a carbon plate could survive mud instead of just marathon pavement. That is the trade a buyer is actually making at that price point, and on this weekend, it held up.
