Back to sprinting:

It's easy to tell if you're a sprinter - if you do a group ride and wonder why no one else sprinted for the sprint at the end of the group ride, you're a sprinter. Or if you think you sprinted to the wrong sign because everyone is so far back and going really slow. Or you sprinted on the wrong lap because no one is sprinting behind you, at least not that you can tell. Or you sit up well before the actual sign/line/whatever because you're already 50 feet ahead of the next guy. Or you're about to jump and you're wondering why everyone is going so slow 100 meters from the line.

Seriously, that'll be your experience if you're a sprinter and you don't know it yet.

If those scenarios seem foreign to you then you need to figure out a different way to try and win races.
