From Addiction Rehab to a 2:38 Marathon - Jack Ahern

Matt Fox celebrates 10 years of Sweat Elite, sharing the story of its beginnings, the successes and failures along the way, and his plans for the future.

Matt reflects on a disappointing Melbourne Marathon after calf pain at 12K developed into a race-ending injury at 20K. An MRI revealed a 15cm grade 3B soleus tear, with evidence of an older injury in the same area—putting his Valencia Marathon plans in doubt.

He shares why he has no regrets about the DNF—and why he wishes he had pulled out earlier. He revisits a calf twinge while testing shoes in May and considers possible contributors to the injury, including training load, trail running, tapering, weight loss and racing in the Puma Fast-R 3. The cause remains uncertain, and his recovery plan is still being worked out with his coach and physiotherapist, Kyle. The listener Q&A covers coping with repeated injury setbacks, keeping base training simple, adjusting training effort in heat and humidity, and finding value in Chinese super shoes. Matt also discusses possible recovery options, including PRP, and shares his views on peptides and anti-doping ethics. There are reflections on Melbourne's elite drink-station setup, Truett Hanes' marathon progress, and Jimmy Wheela's experience racing against Kipchoge. Matt also shares updates on Globe Runners training trips in Monte Gordo and Lisbon, his running shoe distribution business, nutrition coaching, and an upcoming six-month move to Portugal.

In this episode, I announce the next Globe Runners Portugal Running Experience in Monte Gordo, share the results of my latest DEXA scan after dropping from 86kg to around 70kg, and discuss what I learned about weight loss, bone health and nutrition along the way. I also share a remarkable 2:07 marathon performance off less than 100km per week and give my final update before racing the Melbourne Marathon this Sunday.

I explain why I've become increasingly interested in putting my energy into coaching, nutrition and creating running experiences rather than promoting products. A lot of that thinking developed during the months I spent detained in Japan, where I had a huge amount of time to read, write and think about what I actually wanted to work on. The Portugal experience will bring a small group of runners together for eight nights in Monte Gordo in the Algarve. We'll train together, eat together and explore southern Portugal, with optional day trips around the Algarve and to Seville in Spain. The €1,250 price includes four-star accommodation, three meals per day, airport transfers from Faro and transport for the organised excursions. There are only 16 places available. I then get into the results of my latest DEXA scan. In April I weighed 86kg at 22.5% body fat. Around five and a half months later, I'm approximately 70kg and my DEXA measured me at 8.5% body fat. One of the most interesting findings was my bone density. Despite losing roughly 16kg while returning to high-volume marathon training, my measured bone density improved between the two scans. I discuss the things I focused on throughout the process, including calcium-rich foods, vitamin K, vitamin D, sunlight exposure and consistent heavy strength training. I also talk more broadly about weight loss for runners, the genuine risks of low energy availability and RED-S, and why I think the conversation needs more nuance. Losing weight is not appropriate for every runner, but for athletes with excess body fat who want to reduce it, I believe it can be approached carefully while closely monitoring health, recovery and performance. I share an example from one of my nutrition athletes whose weight began dropping faster than planned. When his training performance started declining, we increased his energy intake and quickly got things moving in the right direction again. Then there's a shoutout to Adam Lipschitz, who just ran an incredible 2:07:20 marathon after averaging only around 96km per week over the previous 12 weeks. It's a fascinating example of just how individual marathon training can be and how more mileage isn't automatically better. Finally, it's Melbourne Marathon race week. I talk about where I think my fitness is compared with when I ran 2:18:41, the potential advantage I'm getting from the Puma Fast-R, the weather forecast, and why I believe a significant PB is possible if everything comes together. I also briefly discuss what comes next, including moving to Portugal, racing in Europe and potential starts at Alicante and Valencia later this year.

Topics include losing weight while maintaining training quality, carbohydrate cycling, calorie deficits during a marathon taper, post-workout fueling, finding your ideal race weight, losing fat versus muscle, GLP-1 medications and heart rate, creatine and water weight, and whether the same weight-loss approach can work for shorter-distance runners and triathletes. Matt also shares his own experience dropping from around 86kg to 69kg, how body weight played a role in eventually breaking 2:20 for the marathon, and how he is approaching the final two weeks before the Melbourne Marathon. Later in the episode, Matt gives an update on his Melbourne Marathon goal, testing the Puma Fast-R 3, the upcoming Dynafish launch in Australia, New Zealand and the UK, and his move to Lisbon for six months.

Matt breaks down how to safely lose 5kg+ during a marathon block — using calorie deficits on easy days and big carb windows around hard sessions — so you can train hard and run faster. Matt Fox / Sweat Elite Nutrition Coaching: https://sweatelite.co/coaching/nutrition/ Run + Nutrition Coaching: https://sweatelite.co/coaching/run-nutrition/ Nutrition Meal Plans: https://sweatelite.co/nutrition-meal-plans/ Personalised Training Plan: https://sweatelite.co/personalised-training-plan/ Coaching: https://www.sweatelitecoaching.com/matt-fox/ Instagram: https://www.instagram.com/mattinglisfox/ Strava: https://www.strava.com/athletes/6248359 YouTube: https://www.youtube.com/@SweatElite Sweat Elite: https://www.sweatelite.co/ Matt talks about how to lose five kilograms or more in the ten weeks leading into a marathon — while still training hard and aiming to run faster. He pushes back on the old idea that you should finish all weight loss before the marathon-specific block, and shares how he's used this approach five times himself, including a recent stretch where he dropped nearly fifteen kilos. Matt walks through the method in plain terms: stay in a calorie deficit most of the week, track burn with a watch or rough math, log food with AI photo counting, and then flip into big carbohydrate windows around your two hardest sessions so quality workouts don't suffer. He lands on roughly an eight-hundred-calorie deficit on easy days — enough, on paper, to lose about half a kilo a week and five kilos over ten weeks. Matt is clear this is not for everyone. If you've dealt with an eating disorder, RED-S, or low energy availability — or you're already below a healthy weight — he says turn the episode off. For listeners who can safely lose the weight, he also covers strength work, bone-health basics, and where coaching or a meal plan fits if you want more accountability.

Aimed at people who can safely lose ~5kg+ and want to run faster. The goal Lose 5kg+ in the ~10-week marathon-specific block; Matt's personal and coaching experience; pushback on "never diet in the marathon block." The only rule that matters Calorie deficit = burn more than you eat. Tracking makes it workable; perfection isn't required. How to track burn Garmin (or similar) preferred. Rough guide: ~2,000 kcal/day for many men (5–7k steps); ~1,700 for many women; easy running ~700 kcal/hour; hard running closer to ~1,100 kcal/hour. How to track intake Photo-log every meal/drink in ChatGPT (or similar AI); build one daily log; close enough beats exact. Weekly structure: deficit + carb windows Most of the week (~5.5 days): solid deficit (~800 kcal/day as a working target). Around 2 hard sessions (e.g. Wed + Sun): stop deficit counting ~12 hours before; load carbs heavily before, during, and a few hours after. Hard-session fueling Example carb load ~400g in the pre-session window; in-session carbs often 70–100g/hour for men (women slightly lower); prioritize white rice, potatoes, bread, pasta in those windows. Easy-day eating High-volume, low-calorie foods (fruit, veg, lean protein); flavored soda water as a hunger/dopamine hack; ask AI for satiating low-cal meal ideas. The math (why ~800/day) ~7,700 kcal deficit ≈ 1kg fat; ~3,800/week ≈ 0.5kg/week ≈ 5kg in 10 weeks. Surpluses in carb windows are expected; the weekly total still lands if easy days stay consistent. Injury-risk buffers Start strength (esp. squats) ~1 month before die
