I've noticed a pattern, if Birnbaum is still in it in the final lap, you can already call the race, lol. Here he is at the first high school boys mile at the Drake Relays, but he did the same thing at the 3200m at Arcadia this year (4th --> 1st).
*As good of a runner as Jackson Heidesch is, plus it would've been cool if he won the first high school boys mile at the Drake relays, since he's from Iowa.
