    Power, Confidence, and Success: Behind Pro Cycling with Melisa Rollins

    Take a deep dive into the evolving tactics of gravel racing, where confidence, preparation, and expert coaching drive athletes to new heights. Professional cyclist, Melisa Rollins, and her coach, Isaiah Newkirk, join host Matti Rowe, Education Specialist, for a look behind the scenes of training and racing tactics in professional gravel and mountain bike racing. Melisa, fresh off of a win at Steamboat Gravel and breaking the record at Leadville 100, is redefining how races are won—not just by crossing the finish line first, but by making bold moves and having the confidence to see them through. When she returned to Leadville this year, Melisa brought a new perspective: instead of focusing solely on defending her title, she recognized the unpredictable nature of competition and embraced the value of small victories along the way. Her success comes from strategic planning, adaptability, and a fearless approach to each race, proving that winning can mean much more than a podium finish. Isaiah, founder of TrainingEdge Coaching and performance director for Project Echelon, along with Melisa's coach, dives into the meticulous planning efforts and bold tactical moves—and how Melissa and Isaiah approach everything from training adaptations at altitude to the psychological ups and downs of top-level racing. Key takeaways: If you’ve ever wrestled with motivation after a big win or doubted yourself mid-training session, Melissa’s honest account of post-victory blues and curbside tears offers a refreshingly real perspective. With insights into altitude training, mental resilience, and the power of immediate coach-athlete feedback, this episode is packed with actionable wisdom. Whether you’re preparing for your own Leadville-level challenge or just looking for inspiration to take your training up a notch, Melissa and Isaiah’s story will remind you: success comes from knowing your strengths, planning with purpose, and learning to thrive both in data and what's out of your control. 03:14 Parental Influence and Sport Choices 11:53 Building Confidence Through Specific Workouts 13:58 Racing Strategy & Mental Toughness 17:51 Evolving Race Tactics in Women’s Cycling 19:48 Optimizing Athletic Power Curve 25:15 Remote Coaching's Unique Connection 26:01 Coaching: Beyond Data, Emotional Support 29:20 Leadville Race Experience Insights 36:37 Redefining Winning Beyond Titles 43:36 Altitude Data Boosted Race Performance

    Virtual Crits, Course Recon, and Live Coaching: Redefining Indoor Training

    Hear how structured workouts, virtual communities, and game-changing tech combine for authentic, effective winter training — or cycling in general. George Gilbert and Tim Cusick join host Dirk Friel for a look into the shift of virtual training and how purposeful, science-backed structure can help both athletes and coaches make the most of winter (or year-round) workouts. George, TrainingPeaks’ VP of Virtual Platforms and the mind behind TrainingPeaks Virtual, pulls back the curtain on the fast pace of innovation in the virtual cycling world. From supporting completely custom GPX route uploads, called GPXplore, to immersive, realistic physics for cornering and drafting, the focus is on making indoor training both motivating and specific to real-world cycling. George emphasizes the value of credibility and seamless integration — your outdoor and indoor data, preferences, and progress are all in sync for an experience that works as hard as you do. Tim, founder of Basecamp Coaching and TrainingPeaks WKO product lead, shares how his holistic approach unites expert coaching, nutrition, strength, and mental skills. By leveraging technology and community-driven group workouts, Basecamp delivers individualized plans that encourage consistency and bring the camaraderie of a training camp right to your room or pain cave. Tim urges coaches to lean into building engaging communities, use technology to scale their expertise, and focus on process-oriented growth rather than endless racing or chasing every metric. Key takeaways: Successful indoor training isn’t about generic "spin classes" or chasing the latest trend — it’s about purposeful structure, real-world specificity, and the power of community. Learn about features like Zen mode for focused training, heart rate-based ERG workouts, and dynamic challenge events. Listen in for a fresh look at how tech, expert guidance, and meaningful connection can help you nail your goals — whether you’re prepping for your first century, a bucket-list crit, or want to start your season stronger than ever.

    Scott Johnston's Winning Formula for Ruth Croft and Tom Evans at UTMB

    Scott Johnston, fresh off coaching both the men's and women's winners of UTMB in the same year, shares his coaching philosophy with Dirk Friel. Scott emphasizes the value of consistent, disciplined training rooted in tried-and-true principles. Not through flashy shortcuts, just a thoughtful blend of science, individualized pacing, and real-world adaptability. Throughout the conversation, Scott explains how he tailored training for Ruth Croft and Tom Evans, highlighting that while every Evoke Endurance training plan is built on a shared set of core principles, the real magic lies in personalizing workouts to each athlete's unique needs and life circumstances. Hear how Scott's approach balances rigorous data—like lactate testing and measured thresholds—with the all-important "soft" skills of daily check-ins, building trust, and keeping athletes mentally anchored during major events. One clear takeaway: success is less about pushing past your limits at every session and more about knowing when to hold back, adapt, or shift focus. Scott also dives into the technical side: steep treadmill sessions to build fatigue resistance, the smart use of poles, innovative altitude and heat strategies, and the power of true athlete-coach communication. 00:00 Race Preparation 05:17 Prepared for Rainy Conditions 09:08 Running Takes Backseat to New Priorities 11:00 Speed vs. Endurance Training Balance 15:56 Feared Treadmill Workout 17:04 Lactate-Controlled Workout Intensity 22:54 Technological Advancements Elevate Athletic Performance 24:32 Beyond Data: Understanding Athletes' Internal Load 28:14 Safe Training Limits Prevent Injuries 32:33 Coaches as Essential Partners
