It’s certainly noteworthy and interesting but I could see how Running as sport isn’t popular enough for front page. Especially during NBA and NHL playoffs, NFL draft, and whatever else might be going on.
It’s not meant to be malicious they just don’t report on things that don’t get enough engagement. If you look at the long list of sports they cover, there’s nothing running related even mentioned. They do now have an article on it in their Olympics category as of 2 hours ago. But I feel like them not having a breaking news coverage on a Sunday in this sport is to be expected more so than your expectation of them covering it.
