Fortunately the meet is in a heated indoor stadium and it's tomorrow afternoon when temps will be back into the mid teens. Better buy your tickets soon though, general admission is sold out and there's less than 200 seats left in the gold and silver sections.
"Feels like" temps are just a bunch of BS by the way. When is it ever super cold and not windy? If it's five below and windy, then it feels exactly like every other time I've experienced five below.
