For a recent episode of the Rox Lyfe podcast, we sat down with Alyssa McElheny, one of the fastest-rising names in HYROX after qualifying for the Elite 15 World Championship race in Stockholm within just a few months of entering the sport.
In a short space of time, she’s gone from marathon-focused runner to a genuine contender at the top end of HYROX…
From Heart Condition to 22 Years of Running
As a child, she was diagnosed with Kawasaki disease, a heart condition that, at one point, cast doubt over whether she’d be able to pursue sport seriously at all. But it certainly didn’t stop her. She found running at around 12 years old and stuck with it, and has made continuous, steady progress ever since.
Consistent Progress
McElheny told us that she was a good high school athlete and a solid collegiate runner, earning Division III All-American honours – but her biggest improvements came well after that.
In her late 20s and early 30s, she started to see real breakthroughs. A big part of that came down to consistency and volume. At her peak, she was regularly running between 90 and 105 miles per week for extended periods. Handling that kind of volume as been helped by her durability – she’s only had one significant injury in over two decades.
The 12-Year Chase for Olympic Trials Qualification
One of the clearest examples of her mindset is how long she stuck with her goal of qualifying for the US Olympic Marathon Trials. It took 12 years and multiple failed attempts before she finally got there, running 2:34:27 to secure her place.
What changed wasn’t one dramatic shift. It was a combination of slightly higher volume, better fuelling during long runs, and a more structured approach with a coach. Over time, those small adjustments added up. That patience now carries over into how she approaches HYROX.
Why HYROX Clicked Immediately
McElheny only discovered HYROX in 2025 and went into her first race with almost no preparation. She had to learn movements like sled push, SkiErg and wall balls just days before competing.
Despite that, she was hooked straight away.
That was partly due to the atmosphere at the event but also down to how the race is structured. Her background in steeplechase, where the rhythm is constantly broken up by barriers, translates well to the stop-start nature of HYROX. She also feels the sport suits her physically in a way marathon running didn’t. Compared to most elite marathoners, she’s taller and more muscular, which can be a limitation over 26 miles but becomes an advantage when strength is part of the equation.
Running Still Wins Her Races
Even now, her biggest strength is clear. Her running is what separates her.
She’s still running seven days a week and holding around 55 to 60 miles, even with HYROX training layered on top. She’s kept key elements of her old structure, including a weekly long run that often stretches to around two hours.
In Warsaw (Apr 2026), that background showed. The plan wasn’t to go all-out, it was to qualify for the 2026 World Championships safely. She ran at a pace that felt controlled, close to marathon effort, and stayed within herself the entire race. That approach left her with enough energy to manage the stations effectively and secure qualification without unnecessary risk.
Where She Can Still Improve
What makes her position so interesting is that she’s already competitive, but still has obvious areas she feels she can improve on – her station work in particular.
Early on, movements like wall balls and SkiErg were a clear weakness, and even now she acknowledges she’s not yet at the level of the top Elite 15 athletes in those areas. The difference is how quickly she adapts. She describes herself as highly trainable, able to take on coaching feedback and apply it straight away, which is already showing in her rapid progression.
Mindset Under Pressure
When things get tough, McElheny’s approach is straightforward. She focuses on the next task rather than the whole race. That might mean breaking a station into smaller chunks or focusing on hitting the next distance marker rather than thinking about what’s left.
She also smiles throughout the race, partly because she’s having so much fun, but also because she knows that approach can make her feel better in herself.
Interestingly, she also feels she hasn’t fully hit her limit in HYROX yet. Most of her races so far have felt controlled rather than desperate, which suggests there’s still more to come once she starts pushing that edge.
The Bigger Picture
What makes Alyssa’s story stand out is how grounded it is in reality. There’s no shortcut here. Her success in HYROX is built on years of consistent running, learning from failure, and gradually improving the details that matter.
She may be new to the sport, but the foundation behind her isn’t. That’s why her rise feels sustainable rather than sudden.
