PODCAST
108. I tested how many grams of carbs I really need per hour: Isabella Bertold
I’m joined by Isabella Bertold, a professional cyclist and former world-class sailor, to talk about what happened when she took a test to find out exactly how much carbohydrate her body needed to fuel her cycling—and the results surprised her.
Like many endurance athletes, Isabella assumed she was fuelling well enough. But after taking a metabolic fuel test using EXOAnalytics, she discovered she’d been significantly underestimating her carbohydrate needs. The test revealed she could absorb between 110–128 grams of carbs per hour, far more than the 75 grams she thought was her limit.
107. From Overwhelmed to Empowered: Kate Richardson’s Fuelling Journey
In this episode, I’m joined by GB track and road rider Kate Richardson, who shares how learning to fuel properly has transformed her performance and her enjoyment of racing. Kate recently won the National Elite Women’s Crit Race in the UK, just months after we started working together, and her progress has been nothing short of inspiring.
Kate opens up about the confusion she felt around nutrition before seeking support—being overwhelmed by conflicting advice online and within the sport, unsure how to balance performance goals with health, and wrestling with the taboo that still exists around food and body composition in cycling. Together, we discuss how small but strategic changes have helped her train harder, recover faster, and race with more confidence.
106. Mindset, Mindfulness, and the Ripple Effect of Behavior Change in Sport with Ted Huang
I sit down with two-time Olympic windsurfer and sports psychology graduate Ted Huang to explore one of my favourite topics: behaviour change and mindset. Ted and I recently met on a cycling trip in Italy, and our conversations quickly turned to performance, fuelling, and how psychology underpins so much of what we do in sport and life.
Ted shares his fascinating journey from discovering windsurfing as a teenager, to competing at the Olympic level, and later transitioning into road cycling. He explains how running professional cycling teams and studying organisational behaviour helped him see that athletic performance isn’t just about physical strength—it’s also about headspace, coping mechanisms, and mindset under pressure.
We dive into why so many athletes still struggle with fuelling properly, the fears that hold them back, and the ripple effect that positive changes can have beyond sport. From overcoming the “I don’t need it” mentality, to learning to fuel training better, to understanding how curiosity and self-awareness drive behaviour change—this conversation covers the mental and physical strategies that help athletes (and everyday people) feel and perform at their best.
105. Why did my weight go up?
Have you ever stepped on the scales, seen a higher number and felt your stomach drop? In this episode I unpack why that happens—and why it usually isn’t body fat. I explain the day-to-day variables that move your weight up and down (carbohydrate intake, salt, fluids, travel, big training days and the week before your period), and how to read those fluctuations without panicking or self-sabotaging.
104. Nutrition tips for healthy eating when travelling
Is it possible to go on holidays or travel for work without coming home a few kilos heavier? Absolutely. In this episode of Fuelled, I share practical and realistic strategies to help you maintain your weight while still enjoying travel, conferences, and holidays.
103. Transition from short to long distance Triathlon: Nutrition insights from pro triathlete Grace Thek

Grace recently made her debut at Challenge Roth, and she opens up about how her training and nutrition had to shift to meet the demands of racing long distance.
She shares what it was like overcoming injuries, how she gradually built up her fueling strategy to hit 94 grams of carbs per hour, and why consistency was key to maintaining energy right through to the finish. We also chat about the lessons she’s learned along the way, the importance of practicing nutrition in training, and her advice for new triathletes — from enjoying the journey to being well-prepared on race day.
102. 'I don't need it' - what's that costing you?
I unpack one of the most common phrases I hear from athletes and active individuals: “I don’t need it.” Whether it’s a short ride, an easy session, or a busy day, the assumption that fuelling isn’t necessary can come at a significant cost.

I share the emotional rollercoaster of feeling like a failure, dealing with online negativity, and why I ultimately chose not to give up.
99. Fuelling with Maple Syrup: What you need to know
Can you use maple syrup to fuel your bike rides?
