Being serious now. There is an art and it is fun to watch the kids do it.

As the segment approaches do a spaaz attack off the front. Make sure everyone knows you are trying to show them up and try as hard as you can to get them riled. That will increase group speed 3-4mph. Then blow up. Just act like you had no idea how hard it was at the front and fade to the back. The very back, maybe 1-2 bike lengths as you cross the segment start. Then hang and maybe move to mid acting tired and explode at the top.
It only works a few times per segment, then they have to find another group ride.
