Indoor season is headed our way in the ensuing months, so we're releasing the nation's top returnees in each indoor event over the next few weeks.
A few names you'll recognize are Sam Affolder, Devin Hart and Ryan Oosting.
The runners hail from Loudoun Valley (VA) High School, Pt. Pleasant Boro (NJ) and Arlington (MA) and all own various marks over indoor distance events.
Affolder, though, arrives this indoor season as the top returner in three: 1500m, 1600m and 1-mile.
What kind of efforts will these athletes offer in 2019?
It should be a fun season worth finding out.
In the meantime, check out the top boys returners in the events below.
