How I can help you

Whether you’re preparing for a triathlon or marathon, chasing a faster 5K, stepping up to an ultra, or training for a cycling event like a spring classic or a Gran Fondo in the Alps, I’ve got you. Beginner or advanced, if you’re looking to make real progress with a plan that fits your life, I’m your coach.Every athlete is different. Your pace of life, your schedule, your training load, and your personal goals are unique and your training plan should reflect that. My aim is to help you find the right balance: a plan that fits your lifestyle, supports your ambitions, and sets you up for long-term vitality.There are no shortcuts in endurance. Progress comes from consistency, enjoyment, and staying healthy while not burning yourself out. That’s why I build training plans that are sustainable, personalised, and focused on the long game while keeping the process fun.Each week, you’ll receive a tailored plan in TrainingPeaks that syncs effortlessly with your smartwatch or bike computer. We’ll train using power, heart rate, and perceived exertion, and I’ll support you with nutrition guidance, race strategy, and everything else you need to perform at your best.To keep you progressing, we schedule a monthly evaluation call to review your results, reflect on what’s working, and plan the road ahead. And if you ever have a quick question or want to fact-check something, I’m always available on WhatsApp.In the last 6 years I’ve coached 150+ athletes: from first-time 5K runners to sub-3 marathoners (Men and Women), first-time triathletes to sub-10 Ironman finishers and everything in between.Whether you prefer a simple, no-nonsense beginner plan or love diving deep into data and metrics, I’m all for it.

About me

I'm Benjamin van der Weerdt, 31 years old and I live in Gaastmeer, Friesland together with my girlfriend Floortje and dog Flynn.In 2017 after a turbulent student life, I signed up for my first marathon in Rotterdam. I hadn’t trained properly, knew nothing about nutrition or pacing, and I didn’t even use Strava or a smartwatch. But I loved every kilometre. When I crossed the finish line and let it all sink in, I knew I was hooked and that I wanted to improve.I got myself a coach and started improving year after year and I became addicted to the grind. What began as running only soon grew into cycling and eventually triathlon. I’ve built a solid foundation, stayed injury-free, and steadily improved in all three disciplines. There have been ups and downs, but I’ve always focused on the long game: staying consistent, staying healthy, and enjoying the process. PRs are great, but the reason you get them is usually because you’re happy, balanced, and injury-free.Along the way, more and more people started asking me for help. First friends, then friends-of-friends, and eventually people I didn’t even know. That interest grew, and in 2020 I started Grutto Endurance.I’ve spent years training with a coach, racing often, trying new things, making mistakes, and learning what truly works. Along the way, I dove into the theory behind endurance training, how the body adapts, how to recover, and how to improve sustainably. That mix of 8+ years of experience and solid knowledge means I can help you train smarter and reach your goals.What I love most about coaching is building real relationships, understanding each athlete’s life, goals, challenges, and personality and blending all of that into a training plan that actually works for them. I always look at the bigger picture.Some of my personal highlights:
- 2:38:03 Marathon (Hamburg)
- 1:13:11 Half Marathon (Egmond)
- 33:39 10km
- 8:39:29 Ironman
- 4:06:16 Half Ironman
- 2:00:12 Olympic distance
- Qualified and raced the 70.3 World Championships in 2024 (Taupo, New Zealand)
- Qualified and raced the Ironman World Championships (Nice, France) in 2023.
- Won my age group (30-34) at Ironman 70.3 Westfriesland in 2024 and came 3rd overall.
