Episode 120 — Are You Breathing Wrong? Running, Recovery & Performance | David 'Jacko' Jackson
Send us Fan Mail Could the way you breathe be affecting your running performance, recovery, and sleep more than you realise? In this episode of the 12 Months to Marathon Podcast, I'm joined by David "Jacko" Jackson, also known as The Breath Running Coach, to explore something most runners rarely think about — their breathing. David's story is extraordinary. A former professional rugby player, his career ended following a traumatic brain injury. After a difficult recovery, he discovered the potential of breathwork, rebuilt his relationship with exercise, and went on to become a breathing coach, author of Breathe Smarter, Run Stronger, and take on the remarkable challenge of 100 consecutive ultramarathons. But this conversation isn't just about extraordinary endurance challenges. It's about what everyday runners, particularly those over 35, can learn about breathing, managing stress, and recovering better from training. We discuss: David's traumatic brain injury and how it changed his life. Why breathing is often overlooked in running training. The importance of breathing rhythm, diaphragm function, and running efficiency. Nasal breathing versus mouth breathing — what runners should understand. How breathing techniques may help manage perceived effort during running. The relationship between breathing, the nervous system, HRV and recovery. Why everyday stress can affect your marathon training. Practical breathing exercises to try before running and before bed. What 100 consecutive ultramarathons taught David about fatigue, recovery and managing training load. Why recovery and sensible training progression become increasingly important as we get older. David also shares two practical techniques you can try: a simple five-second inhale and five-second exhale routine before running, and quiet nasal breathing with humming exhales to help you relax after training or before sleep. We also discuss why recovery isn't always about doing nothing, and how understanding your body's response to training can help you make better decisions. The big takeaway? Getting better at running isn't always about doing more. Sometimes it's about understanding your body, managing your stress and giving yourself the opportunity to recover from the work you're already doing. Whether you're training for your first marathon at 40, chasing a PB at 50 or simply hoping to keep running well for years to come, there's plenty to take away from this conversation.
