Over 15,000 people ran the Madrid Marathon last Sunday. Ruben was one of them. He finished in three hours and forty-five minutes, but he didn't go home. He spent the next three hours strategically positioned - 100 metres from the finish line - cheering and supporting every single runner that passed by, calling them by their names, shouting words of encouragement. It was beautiful to watch. His enthusiasm was contagious, and the positive impact on the runners was visible. "I've run the Madrid Marathon eighteen times. I've done New York three times. And Portugal, Japan... I also do Mountain Marathons. I am here to support the runners because I know that it can make a huge difference. Because when I'm running, I appreciate this kind of support from the crowd. The final 100 metres are the most difficult ones. The energy I transmit will help them keep going and cross the finish line."
