Joy Jiang Is Redefining What’s Possible Across Ambitions
Joy Jiang is balancing elite marathon training with the demands of medicine and research
As an MD/PhD student based in New York City, her training exists alongside clinical schedules, research demands, and a life that rarely follows a predictable structure. And yet, she’s built a 2:46 marathon personal best, proving that elite-level performance doesn’t require choosing one path over another.
What sets Joy apart isn’t just her ability to balance it all, but rather how she approaches it.
With a mindset grounded in science, curiosity, and continuous learning, she’s trying to understand how far she can take her running, and how it can evolve alongside everything else she’s building.
TRAINING WITHOUT A FIXED ROUTINE
There’s no perfect weekly structure here. Joy’s training is built around unpredictability. A Tuesday speed session when possible. A Saturday long run with tempo miles when the schedule allows. Everything else shifts depending on where she needs to be and when.
Some days, getting the run in at all is the win.
And that reality brings a different kind of challenge. Joy is often fighting for time and missing sessions, which requires adjusting expectations. And at times, dealing with the quiet voice of imposter syndrome that comes with it.
A SCIENTIFIC APPROACH TO PERFORMANCE
Joy describes herself as a “science girl,” and it shows in how she approaches her running.
Through PUMA PROJECT3, she immersed herself in expert-led sessions on nutrition, shoe design, and sports psychology, using research-backed insights to better understand how her body performs and recovers. She loves the access to resources and learning how to apply them.
With a better understanding of what’s happening within her own body, she is using that knowledge to train with greater intention.
RECOVERY IN THE REAL WORLD
Joy loves sleep. Sleep doesn’t always love her back. She’s the first to say how important it is, and how good she feels after a full night. But with the demands of her schedule, there are times when she gets only a few hours, if she’s lucky
Instead of letting that spiral, she’s learned to adjust.
Some days, it’s about accepting that sleep wasn’t perfect and focusing on what she can still do well such as: eating properly and staying consistent. She doesn’t let one variable define the entire day.
One of her biggest takeaways from PUMA PROJECT3 has been the importance of nutrition for training and recovery. And then there’s the routine that never gets skipped…
Every night, she stretches before bed. Left, right, and middle splits.
SISU: GRIT THAT STAYS WITH YOU
There’s one word that defines how Joy runs: sisu.
A Finnish concept that roughly translates to grit in the face of adversity. It’s something her high school coach once used to describe her, back when she was pushing through 22-minute 5Ks, and it stayed.

ONE PIECE OF ADVICE
