    Why You Won't PR Every Race (And Why That's Okay)

    In this episode, host Stevie is rejoined by fan-favorite and friend of the pod, Coach Nick Klastava. Nick is a dad, husband, running coach, and the brains behind the popular platform Running Explained. If you have ever felt trapped by the numbers on your GPS watch, discouraged because you aren't hitting your college PRs, or lonely in a season of transition, this episode is for you. Stevie and Nick dive deep into "Act Three" of Nick's personal running journey, exploring how he moved from a burnt-out Division 1 athlete to finding genuine, long-term joy in endurance sports. They tackle the toxic comparison traps that many seasoned and adult-onset athletes fall into, why hyper-fixating on your pace splits might be ruining your progress, and how shifting to RPE (Rate of Perceived Exertion) can completely transform your relationship with training. Key Takeaways: The Three Acts of a Running Journey: Nick breaks down his transition from a high-pressure youth and D1 collegiate athlete (Act 1) to a social runner chasing performance in his 30s (Act 2), to his current era of experimenting with mileage for himself at age 44 (Act 3).The Danger of the Comparison Trap: It is incredibly easy to compare your current self to past versions of you. Nick shares how he had to humble his ego and acknowledge that an 18-year-old’s lifestyle demands something entirely different than a 44-year-old father of two.Workouts are for Gaining Fitness, Not Proving It: Why running your goal marathon pace on every single long run during a summer heatwave is a recipe for burnout. Training blocks are cumulative, and you are supposed to feel fatigued.Decoupling Joy from the Numbers: If you only stay in endurance sports to see faster numbers and constant PRs, you will eventually face a joyless experience.The Power of Time-Based Workouts & RPE: How Nick unlocked massive fitness by simply leaving the lap-split button alone and running entirely by feel and effort."If you just live your life by the numbers, you will be disappointed more often than not. The numbers will not be the thing that brings you joy... Finding other ways and decoupling yourself from those numbers is so important." — Coach Nick Klastava Resources & Links Mentioned Connect with Coach Nick on Instagram: @RunningExplained and @nklastavaListen to Nick's first appearance: https://podcasts.apple.com/us/podcast/real-fuel-with-sls/id1746341651?i=1000712227811Learn more about training with Running Explained Stay Connected!
