History - When Mark Threlfall used STEALTH

When GTN Global Triathlon Network Presenter Mark Threlfall was a pro-triathlete he used Secret-Training STEALTH. Mark previously said ‘I’ve used STEALTH nutrition products for a while now and I have really noticed the difference in my performance. It’s reassuring to know that the product range is produced by the very best in the industry, I only work with brands that I genuinely use and believe in' Mark is in no way affiliated to us at the moment and we wish him the best!
