I was a hurdler in high school and mastering stride length was almost the entire point of practicing. It's equally weird to me to see someone claiming to be fluent in English who has never heard the word. Maybe a reminder that we're not as knowledgeable as we think we are and what we choose to consume on YouTube is a tiny smittance of human experience. Running is a fairly universal and important thing for nearly any land animal, hardly a niche thing to talk about, but if you had ever talked to or listened to runners speaking English, you'd have definitely heard them talking about their strides.
