One of the things you can do with a Garmin is find out what your (nearly) instantaneous "best pace" is. Throw a sprint into a run and afterward you can find out what pace you hit. Training for speed recently, I took forever getting from 3:38 per mile down to 3:35. Given that some milers run nearly that fast not just for a second, but for an entire mile, reminds me of how much I've slowed over the years. A couple of days ago I finally got to 3:27. Felt good...
Then I heard about Usain Bolt at the Penn Relays. 100m split in 8.79 seconds! That's 2:21 per mile pace! I'd add the video here, but there's a glitch preventing it right now. Here's the link (the link says it was 8.74)
8.79 Are we even in the same sport?
