  • Great Running Pod

    This is a great podcast for anybody serious about running.

    There are so many podcasts out there that provide little value and include questionable training information. Here, you get the science, the methods to apply it, and the experience of extremely good runners.

    All that being said, you do not have to be super fast to find this podcast useful. The information is helpful to anybody serious about training and improving.

Talking Points

Recent interactions between the hosts and their guests.

Breaking down Dan's PhD
Q: Could you have a portable device that can measure lactate and IL-6?
A rapid point-of-care IL-6 test could help track the stress of longer runs, where lactate may not reflect duration-related strain. Current testing requires venous blood processing and is too expensive and slow for routine use.
Breaking down Dan's PhD
Q: Can we use these components as biomarkers for acute stress during exercise or training adaptations or training tolerance?
The study monitored IL-6, soluble IL-6 receptor and SGP-130 alongside training, well-being and performance data. IL-6 rose during an hour of running, correlated with perceived effort, and its response was smaller after eight weeks of training. The other markers produced less immediately useful findings.
Understanding body composition - with Dr James Fleming
Q: What do you mean by intentional eating, and how can athletes apply it in practice?
Intentional eating means planning meals and timing around training demands, aiming for meals that support performance and recovery, and coordinating this with sleep, stress, and overall health; it involves working backward from training sessions to determine when and what to eat, rather than leaving nutrition to chance.
REDS & Running Social Media - with Sian Secc
Q: Owain asks about the balance between social media and education—how should listeners approach this content?
Listeners should critically assess who the content is from, check qualifications, and rely on long-form, evidence-based sources; block or mute content that makes them feel inadequate and seek guidance from registered professionals when in doubt.
REDS & Running Social Media - with Sian Secc
Q: What would you say are the traffic light systems for what to look out for if you are starting to develop red S?
Look for red flag behaviors such as waking at night, social withdrawal, relentless training with insufficient rest and fueling, brain fog, fatigue, and poor recovery; these should trigger a closer health check, blood panels, and consultation with a RED-S specialist.
