Everything Ultramarathoner Emily Halnon Wears While Running

Welcome to On the Run, a Strategist column where we ask discerning runners to tell us everything they wore and brought on their most recent run, from shoes and socks to headphones and energy gels. Running-gear preferences are very personal and change depending on the season, so instead of declaring one pair of shorts or one sports bra the categorical best, we hope this series captures what works best for one particular runner on one particular run — and that maybe you can find something in it that works for you, too.

For this installment, I spoke with writer and runner Emily Halnon, who holds the record for the fastest known time running the Oregon section of the Pacific Crest Trail, covering 453 miles in seven days and 19 hours (or an average of 57 miles per day). Halnon took on the challenge in honor of her mother, who died of cancer last year. She ended up raising over $34,000 for the Brave Like Gabe foundation, created by the late professional runner Gabriele “Gabe” Grunewald to fund rare-cancer research. When she’s not running, Halnon writes about her outdoors adventures in her newsletter, Trail Mix. Here, she shares everything she wore and brought on a 50-mile run in the Grand Canyon on a hot and sunny day this May.

While Halnon says everything she owns from women’s running brand Oiselle is “high-quality and reliable,” for running in the Arizona heat, she especially likes this “light and airy” tank top that keeps her as cool as possible. (For colder days, I’m a fan of the brand’s long-sleeve shirts, which feature an ingenious “watch window” for viewing your GPS watch while keeping your hands warm.) “It’s easy to want to support Oiselle,” says Halnon, “because they’re doing really important work in the running community driving conversations around social justice and equality.” For example, last fall, the company organized a Womxn Run the Vote Relay, a virtual relay race raising money for Black Voters Matter.

“BOA is actually a short that I was first attracted to because they’re so fun,” says Halnon of the California-based brand known for its wild styles like trompe l’oeil denim or colorful donut-patterned running shorts. Both she and her friend Eli, who ran with her in the Canyon, wore BOA shorts on this run. “We both like to wear really fun things while we’re doing these hard things because it reminds us that we’re out there for fun, and that we can insert a lot of fun and joy into these really hard and rugged runs and adventures that we do,” she says. Beyond their playful looks, Halnon adds that she’s impressed with how these shorts can “hang for long distances,” and she’s worn them on runs as long as 100 miles. “They’re so comfortable, they don’t chafe, they’re made of this flowy, barely-there fabric, and they’ve got a nice generous split on the side,” she says.

Halnon admits that in her first 100-mile race, her socks were “an afterthought” and her feet paid the price. Afterwards, she made the effort to research and test out socks that wouldn’t leave her with painful blisters and determined that Stance crew-length socks worked best. “For most long-distance runs, Stance socks do really well with my feet and [help with] avoiding blisters or any other foot issues,” she says. These socks are also favorites of Harlem Run co-founder Amir Muhammad Figueroa and running coach David Roche.

Since most of her runs are off-road, Halnon wears a dedicated trail shoe that offers more traction on uneven terrain. Altra shoes are recognizable for their wider toe box, which she and other runners tend to like. As running coach Tiffany Carson England once told us, the Altra Timp shoe “allows your toes to move more freely and splay out naturally, which can help keep your balance on the trails.” For Halnon, it’s the balance of soft cushioning and support that makes these her go-to shoes. “I run a lot of miles so it’s good to reduce some of the impact through that cushioning,” she says, “but you still feel connected to the ground in these, and they’re really responsive.”

Engraved with the words “Stay Brave,” this bracelet originally belonged to Halnon’s mother, who bought it after being diagnosed with cancer. Halnon now wears it whenever she’s running, and it felt especially significant during her Pacific Crest Trail run. “The whole run was inspired by my mother and wanting to celebrate what an incredibly brave woman she was and what a really bold and beautiful life she led,” she says. “I wanted to do something in that spirit, and running across Oregon was that thing. It means a lot to look down at my wrist and have this reminder of my mother and of the ways that I want to keep honoring her through the things that I do.”

When you’re out on the trails for hours at a time, a hydration pack with plenty of pockets for other essentials is a must-have. Halnon says this is the one she — all of her ultrarunning friends — uses because it can fit a lot of gear inside and doesn’t bounce or chafe when she’s wearing it. Besides a full tank of water, she likes to fill her pack with snacks, like Sour Patch Kids, Rice Krispies Treats, and peanut butter M&Ms, to fuel her runs. “When you’re running long, it’s really easy to stop eating and to end up in an energy deficit, but when you have snack breaks that are full of things you look forward to, it’s much easier to keep eating,” she says. She also stashes a Katadyn water filter that removes contaminants from lake and stream water so she can refill her hydration pack in the wild, and the lightweight, water-resistant Patagonia Houdini jacket in case the temperature suddenly drops or she’s caught in the rain.

For long, mountainous trail runs — like this trek across and back the Grand Canyon — Halnon uses these poles for added stability. She first started using them when running in the “relentlessly steep” San Juan Mountains of Colorado. “They just give you a little bit of extra oomph on uphills,” she says, “and for some extra balance on technical downhills.” She particularly likes the Black Diamond model because they fold down small enough to fit in her pack when she doesn’t need them.

“I got my Garmin inReach a few years ago, and it was a piece of gear that made my mother very happy because its primary purpose is for safety,” says Halnon of this satellite-based communicator that lets her send messages even when she’s deep in the woods without cell service. The inReach has a button that will trigger a search-and-rescue operation and broadcast her location in case of emergency, and it was also pivotal for Halnon’s support team to track her during her Pacific Crest Trail run and let her alert them if she needed an extra layer or more food along the way. While most runners might know Garmin for its GPS watches, Halnon says when it comes to watches, she actually wears a Coros model because its “ridiculous” battery life can stand up to her extra-long expeditions.

Like her BOA shorts, Halnon says she was first drawn to Goodr sunglasses (the brand is a sponsor of her newsletter) because they’re fun and colorful. “They’re also super-functional,” she says, noting that they never slip or bounce around on her face when she’s running or doing other sports like skiing, mountaineering, or climbing.
