The 2018 Mullen Invitational was stacked with a stellar performances across the board. And while it's highly unlikely we'll see Anna Hall this year (she's competing at Arcadia), let's flashback to when she dropped a 42.03 in the 300 hurdles, which was the No. 2 mark in the country at the time.
Hall went on to run a US No. 3 40.76 in the event at the state meet, which was the all-time Colorado record for about three minutes.
