Trifle it's just a school sports day....
Did you even read the article? It's not a race at sports day. It's a place on the varsity track team that this boy has been encouraged to take from another girl. That's a big deal in high school. The camaraderie of the team, physical training with coaches, travelling for meets, a positive thing to include on university applications...
I was a (mediocre) track runner in high school, and I remember very clearly how hard I worked (many of us did) to make varsity team and how proud I was of myself when I finally did in my third year. I still have the 'letter' jacket thirty years later, it's such a fond and vivid memory.
Beyond the place on the team that he's taken from a girl in his own school, this boy will be taking an earned sporting achievement from every girl he "beats" in a race for the next four years. If he's the fastest one running those races, he'll take the achievement of being named State Champion, Regional Champion, National Champion, from four different girls each year he runs. He may well take scholarship opportunities away from them.
It isn't fair. Maybe it wouldn't have been important to you, and maybe you wouldn't care if it was your daughter who lost her place on the team, but it isn't just a plastic medal at sports day.
