In his fifth attempt, Koji Murofushi had his best mark of the day at 76.42 meters. And after the competition was over, he left the field with a satisfied smile, waving to the fans in the stands at Tokyo's Ajinomoto Stadium.

The figure seems far from spectacular for the Olympic and world championship gold medalist, whose personal best is 84.86 meters.

But as much as achieving a big feat like winning a gold medal at a world championships or setting a new personal best, Murofushi wants to prove that anyone can compete at the highest level for many years with the right training and motivation.
