Leonard Arnold
Professional Triathlete
I’m Leonard Arnold, a German professional triathlete from Potsdam. I approach the sport with the same mindset that shaped me as a mechanical engineer: staying curious, focusing on the details and continuously improving the system. Known as “Locomotive Arnold” in my home region, I have worked my way from age-group racing to competing at the highest level of long-course triathlon while staying grounded in where I came from.
