Here are a few events and storylines we’re following. 

Isaiah Harris Returns To The Track

What: Men’s mile, men’s 4x400

When: 12:15 PM ET, 4:55 PM ET

Why: NCAA 800m runner-up Isaiah Harris will make his first appearance on the track since he ran at the 2017 World Championships in London. The Penn State junior ran a lifetime best of 1:44.53 to finish second at the U.S. championships and earn a berth on the national team. On Saturday, he will be racing the mile and running a leg on Penn State’s 4x400. 

Dominic Perretta is set to pace a mile field that features Harris, former Nittany Lions Cas Loxsom and Robby Creese, Villanova’s Logan Wetzel, and Penn State’s Timothy McGowan. Harris will be looking to improve on his personal best of 4:05.89, while Loxsom will be running his first race since last July according to Tilastopaja. Loxsom and Harris both broke the indoor 600m world record in an exciting race last winter at Penn State.

Since then, Loxsom left the Brooks Beasts group in Seattle and relocated back to State College. 

At the end of the meet, Harris will also be able to get some speed work in. His Penn State 4x400 will run against teams from Villanova, Georgetown, Cornell, Pittsburgh, Virginia Tech, Iowa State, Bucknell, and Maryland
