How many threads do you see here about sprinting? We mostly talk about distance running. When we talk about a kind of equipment we might use it's equipment for distance running. When we talk about a brand disappearing we usually mean from the sport of distance running and don't feel the need to specify because nearly everyone understands that here "running" means distance running unless otherwise specified except for very small number of posters who seem to feel the need to try to look more clever than everyone else. Again, we all knew what brand Bolt was running in. You did not add any new information by mentioning it.
