4:01.65! A US No. 1 Mile For Cruz Culpepper At UW Invite

The gauntlet has been thrown!

Cruz Culpepper ran the fastest mile in the country Saturday night at the UW Invite in Washington. 

The Niwot senior dropped a big personal best of 4:01.65 and could be the first athlete to threaten the sub-4 barrier in 2020. 

The time is a US No. 1 by a staggering eight seconds, and is the fastest by a high schooler since Brodey Hasty ran 4:00.05 in 2018. 

Of additional note -- that's the fastest by a Colorado high schooler, ever.

Let the chase begin!
