Why and how she started 100-mile weeks

In this episode, I’m joined by Sydney Park — a 21-year-old ultrarunner who ran her 100-mile debut in under 20 hours, stacks 100-mile weeks, and is fully committed to chasing a professional career in ultrarunning.

What makes Sydney special isn’t just her results — it’s how she trains and how she thinks.

We talk about how she went from not even knowing what an ultramarathon was at 18… to racing sub-20 at Javelina, winning ultras, surviving backyard races, and building a level of consistency most runners struggle to find.

We dive into:

• How she structures 100-mile weeks without burning out

• Why running easy actually matters more than people think

• How she uses doubles to increase volume safely

• The strength training staples that have kept her nearly injury-free

• Why flexibility beats rigid discipline in long-term training

• The mental framework she uses when races get hard

• How chasing a big goal changed her confidence and identity

• Why keeping promises to yourself is the real key to consistency

This episode is for runners who want to:

• Train smarter, not just harder

• Build consistency without obsession or burnout

• Think bigger about what’s possible in the sport

• Stop underestimating themselves

If you’re chasing big goals — or afraid to even say them out loud — this conversation will change how you approach your training.
