Ultra runner and women’s wellness coach Frankie Smyth set out to run 50km in all 15 UK National Parks in 15 days. In this episode of The RunThrough Podcast, hosted by Ben Sheppard, Frankie shares the full journey — from the spark of inspiration to the moment she crossed the final finish line.
She talks about why she took on such a huge challenge, what she learned about resilience, and how the experience pushed her physically and mentally. Although she ultimately completed the challenge, Frankie opens up about the tough decision to adjust her distances on a few days due to injury, fatigue and safety — and why adapting the plan was essential to reaching the end.
We dive into the logistics behind a multi-day endurance challenge, the highs and lows of life on the road, the support she received from friends, family and strangers, and the emotional finale surrounded by the Alfie Nick Foundation, the charity she ran for in memory of her cousin’s son.
If you need a reminder of what you’re capable of, this episode is it.
