The answer might surprise you. After a tough weekend in the Colorado mountains, I learned a valuable lesson that had nothing to do with breakfast and everything to do with fueling your body the right way. While training for HYROX, I attempted an 11-mile alpine trail run after skipping breakfast. The climb felt amazing, but the descent quickly exposed a mistake that cost me performance, energy, and confidence. In this episode, I share exactly what happened, why I started cramping, how two simple salt capsules completely changed the rest of the run, and what every runner, hiker, endurance athlete, and HYROX competitor can learn from this experience. If you've ever wondered whether fasted training is right for you, or you're looking for practical endurance nutrition tips, this episode will help you make smarter fueling decisions so you can perform at your best. In this episode you'll learn:- Whether skipping breakfast is actually the problem- Why salt and electrolytes matter more than many athletes realize- How carbs, calories, and hydration work together during long efforts- Lessons from trail running, ultramarathons, and HYROX training- Simple ways to fuel your next long run or mountain adventure Chapters:00:00 Welcome to Athlete With Asthma show00:44 Can you trail run without breakfast?00:55 HYROX training and mountain plans01:58 Why mountain running inspires me02:45 My no breakfast fueling strategy05:04 Strong climb, tough descent06:18 The salt deficiency breakthrough08:22 The real lesson about endurance fueling10:47 Final thoughts and an invitation to join Athlete With Asthma healthy living guide I'm Jonny Havey, the Athlete with Asthma, and I help people with (and without) asthma overcome their perceived limitations and achieve elite health and performance, without relying on quick fixes, crash diets, or constant inhaler use.
