Jan Frodeno had swum 3.86 kilometers, then pedaled 180 kilometers and finally ran a marathon.
Nothing unusual for the 39-year-old.
Frodeno is a triathlete, the best in the world.
He does this more often.
But this time, on April 11th in Girona, he had not moved 50 meters during the eight and a half hour procedure.
And had even been accompanied by thousands of other athletes in his last two disciplines.
They all sweated like the German professional himself in their own four walls or in the gym.
What was first made available to the masses in 2006 with the Nintendo Wii has evolved into an increasingly realistic simulation of movement and performance.
Especially for the amateur athlete.
With many advantages.
