In this episode, Dennis sits down with extreme triathlete Niklas Hoff Sekkelsten from Norway to explore what it really takes to compete at the highest level — and what happens when everything suddenly stops.

After a serious injury forced him out of training for 4 months, Niklas faced one of the toughest challenges of his journey. No racing. No progress. Just uncertainty.

But instead of giving up, he focused on something most athletes overlook — his mindset.

Together, Dennis and Niklas dive into:

This is more than a triathlon story — it’s about resilience, discipline, and what it truly means to push beyond limits.

After completing a half marathon, we took time to reflect — not just on the result, but on what it reveals about our preparation for the upcoming Ironman in 83 days.

This conversation goes beyond performance. It’s about identifying gaps, adapting strategy, and making smarter decisions under time pressure.

Sometimes progress starts with a reality check.

Triathlon is getting closer. With 94 days until the triathlon, Dennis and Chris sit down to talk honestly about their preparation, expectations, and the challenges ahead.

From balancing training with everyday life to building consistency in swimming, cycling, and running, this episode dives into what the next three months will really look like. No perfect plans — just the real process behind preparing for the day.

Whether you're training for your first triathlon or already deep in the sport, this conversation gives you a transparent look at the mindset, struggles, and strategies that come with the countdown to competition.

Your race day nutrition doesn't matter if you're eating garbage the other 360 days of the year.

In this solo episode, Dennis breaks down daily nutrition for triathletes with real jobs and real lives. The real calorie math (why 40% of amateur athletes are under-fueling), a simple plate method that requires zero calorie counting, the hydration mistake that costs you 7% performance, and 5 common nutrition fails — including why cutting carbs while training for triathlon is like removing the fuel tank from a car.

Think triathlon is a rich person's sport? The average triathlete spends $3,500/year — but you can get started for under $500.

In this solo episode, Dennis breaks down the real costs of swim, bike and run gear, shares 5 proven budget hacks (buy off-season, join a club, ditch the supplements), reveals where you SHOULD spend money, and tells the story of racing his first triathlon on a city bike with a basket.

Key insight: The best investment in triathlon isn't gear — it's consistency. A $500 bike ridden five days a week beats a $5,000 bike ridden once a week. Every time.

Whether you're a complete beginner or looking to cut costs, this episode has real numbers and real tips to make triathlon accessible.

Chris and Dennis share their experiences with regular sauna and cold plunge sessions in Kraków. Both have noticed less muscle soreness, fewer physiotherapy visits, better sleep, and strong mental relaxation benefits.

🧊 Cold plunge takeaways: Studies show ice baths feel good but don't truly speed physiological recovery — only short-term soreness relief. Longer or colder isn't better, and cold exposure right after hard strength training can actually block muscle adaptation.

🔥 Sauna takeaways: Research is strongly positive. A 20-year study found 4–7 weekly sauna sessions significantly reduce cardiovascular and all-cause mortality. Sauna also improves vascular function and produces adaptations similar to endurance training. 

✅ Verdict: Cold plunge is a nice-to-have recovery tool but shouldn't be overdone after intense sessions. Sauna has clear long-term health benefits. Sauna Sunday stays! 

TL;DR: 🔥 Sauna = proven long-term health & longevity benefits. 🧊 Ice bath = feels great, helps with soreness, but don't overdo it after hard training. Listen to your body! 🧠💚
