If your training isn't matching your effort, low iron could be the missing piece.

What You’ll Learn * Why repeating similar rides eventually stops producing meaningful improvement * How speed and FTP can mislead you about your actual race-day fitness * Why cycling frequency, durability, and pacing matter more than simply riding harder * How outdoor skills, position, strength, fueling, and pedal efficiency turn fitness into performance Timestamps 00:00 Why triathletes struggle to improve on the bike 03:35 The factors that drive cycling progress 08:00 Why every ride should not look the same 12:00 Using progressive overload in bike training 28:00 Why average speed is a misleading metric 38:15 FTP versus sustainable race-day power 41:20 The problem with making every ride hard 46:45 Why triathletes may need to ride more often 1:00:45 Why indoor fitness does not fully transfer outdoors 1:05:30 Position, strength training, and functional bike power 1:11:35 Fueling the bike to support the run 1:14:25 Pedal efficiency and bike-handling fundamentals For coaching inquiries: Coach Katie → https://fuel2run.com [https://fuel2run.com] Coach Justin → https://tabularasaracing.com [https://tabularasaracing.com/] Podcast Email → theenduranceathletejourney@gmail.com [theenduranceathletejourney@gmail.com]

Road to Grandma’s Marathon: Marathon Recap- A Lesson in Grit

Send us Fan Mail [https://www.buzzsprout.com/2450527/fan_mail/new] In this episode, Katie shares a candid recap of Grandma's Marathon and reflect on one of the most challenging races of my running career. After beginning training with hopes of running a personal best, an unexpected bout of Influenza B just eight weeks before race day changed the trajectory of her marathon build. Despite working hard to regain fitness, lingering doubts followed her into race day, forcing her to confront difficult questions about expectations, motivation, and what success really means. Katie takes you through the highs and lows of race weekend—from travel mishaps and pre-race stress to the mental and physical battles that unfolded over 26.2 miles. What began as a pursuit of a sub-3-hour marathon gradually became a fight simply to reach the finish line. In this episode, Katie discusses: • Recovering from illness during a marathon training cycle • The challenge of adjusting goals after a major setback • Confirmation bias and why athletes sometimes ignore warning signs • The difference between intuition, fear, and self-doubt before a race • What happens when your race-day reality doesn't match your expectations • The mental battle of continuing when every part of you wants to stop • Why difficult races often teach us more than successful ones • Re-evaluating performance goals, aging, health, and longevity as an athlete • Finding new ways to pursue growth and joy in endurance sports This conversation is about much more than one marathon. It's about learning to adapt when things don't go as planned, finding pride in perseverance, and redefining success when the original goal slips away. Whether you've experienced a disappointing race, struggled through a setback, or are questioning your own athletic goals, this episode offers an honest look at resilience, self-reflection, and the lessons endurance sports can teach us. Sometimes the greatest victory isn't achieving the goal you set out to accomplish—it's finding the strength to keep moving forward when the race becomes something entirely different than you expected.
