The last event was the 400-meter relay race, that had promised to be an exciting one. And so it was! Teams from every class joined in the race, but the winning team would be the champion of our school! So each player tries hard to win. The big crowd became quite silently and all of them had their eyes were focused as the team took their places.

Our class took a first place. Everyone cheered wildly and we felt extremely proud.
