    Episode 33 - The Older You Get, the More Expensive an Injury Becomes (opens the original)

    Episode notes

    Read excerpt

    Episode 33 explores running injuries through a simple risk-management lens: Risk = Probability × Impact . The central idea is that ageing does not automatically make runners fragile or guarantee a higher injury risk, but the consequences of a significant injury can become more costly because rebuilding lost strength, fitness, tendon capacity and race-specific durability may take longer and disrupt a larger proportion of our training. The episode argues that our risk appetite should evolve with a

    Episode 32 - Cardiac Drift: Why Your Heart Rate Rises When Your Pace Doesn’t (opens the original)

    Episode notes

    Read excerpt

    In this episode of The Trail Running Briefing, we explore cardiac drift: why heart rate can gradually rise during long runs even when pace or effort appears unchanged. We explain the relationship between heart rate and stroke volume, why heat, dehydration and prolonged exercise increase cardiovascular strain, and how this matters specifically for ultrarunners. We also look at aerobic decoupling and durability, and discuss how pacing, consistent aerobic training, progressively longer runs, sensib

    Episode 31 - Peak Form: How to Reach It and Why You Can’t Stay There Forever (opens the original)

    Episode notes · Neutral tone

    Read excerpt

    Peak form is not simply about being as fit as possible. It is the point where high fitness meets low fatigue, allowing an athlete to fully express the adaptations built over weeks and months of training. Hard training develops aerobic fitness, strength, durability, climbing and descending ability, but it also creates fatigue. This means runners can sometimes be getting fitter while temporarily feeling slower or heavier. Tapering works by reducing that fatigue while preserving the fitness already

    Episode 30 - The Plateau Problem: Why Ultrarunners Stop Improving and How to Move Forward (opens the original)

    Episode notes

    Read excerpt

    In Episode 30 of The Trail Running Briefing, we explore why ultrarunners sometimes stop improving even when they are training consistently and working harder. A plateau doesn’t always mean you need more mileage or more intensity. It can mean your body has adapted to the same training stimulus, accumulated fatigue is hiding your fitness, recovery or fuelling is insufficient, or your training is no longer targeting the qualities that actually limit your performance. We look at the importance of pu

    Episode 29 - When More Becomes Too Much: Burnout in Ultrarunning (opens the original)

    Episode notes · Neutral tone

    Read excerpt

    Ultra running demands far more than just mileage. Long runs, back-to-backs, strength work, fuelling, recovery, work, family and everyday stress all contribute to the total load an athlete carries. In this episode, I explore burnout in ultrarunning , how it differs from normal fatigue or overtraining, and why it can gradually turn something we love into something that feels like an obligation. We look at the key warning signs, physical and emotional exhaustion, declining motivation, reduced sense
