In episode #175 we discover how one of the world's top ultrarunners, Manuela Vilaseca, trains, fuels, and recovers for back-to-back 200-mile races. She shares her secrets on managing nutrition in ultra-distance events, strategies for mental resilience, and balancing a busy coaching career with endurance pursuits

• Breaking the Triple Crown 200 series record in 2025, and managing mental focus as a full-time business owner and coach
• Nutrition strategies: real food vs sports nutrition
• Overcoming GI issues
• Hydration management: balancing salt intake and managing sweat loss
• Recovery habits post-race: yoga, mobility, and mental strategies

Manuela Vilaseca is one of the most accomplished trail and ultra runners in the world, with a long, diverse history in sport, competing since 2011. With two top 10 finishes at the Ultra Trail Mont Blanc, a top-ten Ultra Trail World Tour ranking, multiple wins, course records, and podium finishes, as well as most recently crushing the record for the Triple Crown of 200s in 2025, she is truly one of the most versatile athletes in the sport.

Born and raised at sea level in Brazil, Manu has a unique ability to compete without training at altitude, separating her from others in the front of the pack. She attributes this ability to her multi-disciplinary training which includes trail running, cycling, and yoga. Manu's lifetime of experience has helped her become fluent in English, Spanish, Portuguese, and Catalan. She is a United Endurance Sports Coaching Academy certified coach with Peak Run Performance coaching team, where she works with athletes from all over the world in multiple languages. She is also a certified personal trainer and yoga instructor. She enjoys sharing what she has learned through her own running journey and finds immense value in sharing her training philosophies, multi-sport approach and means of maintaining a positive mindset with her athletes.

In episode #174 we discussed Dr. Jose Areta's latest research, including:

• How energy deficits influence muscle protein synthesis and quality
• The role of mitochondrial proteins and their upregulation during energy restriction
• Practical implications for timing and periodization of caloric deficits in training cycles
• Hormonal signals and their interaction with muscle adaptation during energy deficits

Associate Professor Dr. José L. Areta is a leading scholar in Exercise Metabolism and Nutrition in the School of Sport and Exercise Sciences at Liverpool John Moores University (LJMU). His research investigates how nutrition and exercise interact to influence both performance and health. He focuses on the timing and composition of macronutrients — carbohydrates, proteins, and fats — and how they affect training adaptation. José also examines the role of dietary supplements in optimizing athletic performance, as well as the endocrine and metabolic consequences of energy restriction, particularly low energy availability. He has contributed influential studies on how severe calorie deficits combined with exercise can alter muscle quality and metabolism. José’s work links cellular-level changes in muscle to practical nutrition strategies for athletes facing weight-sensitive sports or energy restriction.

In episode #168 we talked with Dr. Steven O'Bryan about

• Age and sex hormone impacts on female neuromuscular function and performance
• How muscle contractions and force can change over time
• Postmenopausal hormonal changes and muscle strength and contractility

Dr Steven O’Bryan is an internationally recognised neuromuscular physiologist whose research explores how sex-specific ageing, age-related disease, acute exercise, and long-term training adaptations influence the integration between the brain, spinal cord, and skeletal muscle. His work aims to develop innovative, evidence-based strategies to enhance physical function and performance across the lifespan. Dr O’Bryan is an expert in a range of advanced neurophysiological techniques, including electrical and magnetic nerve stimulation, transcranial magnetic stimulation (TMS), electromyography (EMG), and assessments of skeletal muscle force and power. His research bridges mechanistic physiology with real-world applications in clinical, athletic, and ageing populations.

• His published study, "Efficacy and safety profile of oral creatine monohydrate in add-on to cognitive-behavioural monohydrate in depression: An 8-week pilot, double blind, randomised, placebo-controlled feasibility and exploratory, placebo-controlled feasibility and exploratory trial in an under-resourced area"
• Where he'd like to see additional research 

Dr Riccardo De Giorgi is Clinical Lecturer at the University of Oxford, Department of Psychiatry, and ST6 at Health Education England-Thames Valley, Oxford Health NHS Foundation Trust. He is interested in neuropsychopharmacology and evidence-based treatment of mental illness, especially mood disorders. He works on evidence synthesis, epidemiological, and experimental medicine studies to investigate repurposing opportunities for drugs with immuno-metabolic activity (e.g., statins, GLP1-RAs) in psychiatric disorders.

To close out 2025, we are replaying a couple of our most popular episodes, starting with our conversation with Kilian Korth, ultrarunner and expert in the 200-mile distance, who set the record for the Triple Crown of 200s in 2025.

Kilian Korth lives and trains in Western Colorado, spending time traversing mountain ridges and desert canyons alike. He is an ultra runner and full time coach, focusing on the 200 mile distance and other multi-day efforts. This weekend he became the Moab 240 champion AND Triple Crown Winner, setting a new record after winning the 2025 Bigfoot 200 and Tahoe 200. We chatted with Kilian about some interesting nutrition and mindset strategies he uses, as well as achieving this monumental goal. Other notable running achievements include:

• 1st place, DC Peaks 50 Mile, 2022
• 1st place, Mogollon Monster 100, 2024
• 1st place, Red Rock Canyon 100K, 2024 
• 2nd place, Bigfoot 200, 2023

Ultimately he wants to evolve and strive toward longer and longer distances, eyeing some of the notable long trail FKTs in the United States and elsewhere, like the Colorado Trail, Pacific Crest Trail, and Appalachian trails.
