Jordan McNamara leads the way with a 3:54.27 at the Nike Festival of Miles.
Thursday marks the 50th anniversary of Jim Ryun’s record mile run as a high schooler.
The miler is hoping for a low-3:50s race on Saturday night.
Also in the mix is event-record holder Jordan McNamara.
At least nine runners have broken Roger Bannister's famous barrier.
He's been named an honorary coach.
