lean forward at the end! you or your son probably already knew that, but incase you didn't, leaning doesn't help you shave off time as much as win when you're neck in neck with someone.

Try extending your arm so its straight at the hand off. thats how our girls got the record.(:

My 4x200 team just beat the school record by 2.5 secs. I am third leg but I have ran the first leg before. Make sure he knows what his lead foot is, and make sure he doesn't come right up when he explodes out of the blocks, that can make his time longer. And for the hand-off I don't know what to tell you for his split time, but if you want the team to do good, I would do the 3 pump method. The 3 pump method is where the person receiving the baton will start sprinting and count 3 pumps to the left arm, and then on the 3rd pump put his left arm straight back so that the person can lay it right in his hands and he won't have to turn. We used to just stand there take the baton and run... Trust me, the 3 pump helps A ALOT.
