Start an all-time list. A top 10 would be great, it gives the slower guys motivation.
We had one in high school and everyone loved it, we'd study it all the time and think about what we could do to get on it.
The new coach came and refused to let us hang it up, big asshole. The team is now dead last in the league and I'm not surprised.
The old top 10 list was just a computerized printout, our coach kept track of everything and posted a new printout whenever something changed.
He also gave us printed results of our performances at track meets so we could see everyone's splits and how they did. Big motivation for me to see the fastest guy on our team running such fast times.
