The Prefontaine Classic will move to Stanford this summer as construction of Hayward Field forced Eugene’s annual international track meet to find a new venue for 2019.

According to sources, the official announcement will come at the Feb. 5 TrackTown Tuesday town hall-style gathering at the Downtown Athletic Club.

The Pre Classic, held every year since 1973 at Hayward Field, will take place June 30 at Cobb Track and Angell Field.

Capacity at Stanford’s home track is listed as 1,772 with limited ability to increase seating, though temporary bleachers are expected to bring capacity closer to 5,000 for the only IAAF Diamond League meet held in the United States.

Attendance at Hayward Field typically exceeded 10,000 for the Pre Classic.

Longtime Pre meet director Tom Jordan wouldn’t confirm Stanford as the 2019 location, though he said several unspecified sites in Oregon were considered.

Sources said the Pre Classic gave serious thought to holding the meet at Lane Community College, which has an IAAF-approved track.

Representatives from Nike, which funds the meet, and NBC, which airs the meet, toured Lane’s facilities last June but it was eventually determined the cost to upgrade the track for a live TV broadcast and temporary seating was too expensive. Lane has no seating at its facility, just a berm that horseshoes the track.

Facilities at Lewis and Clark college in Portland and at Oregon State were also considered.

The Pre Classic is expected to return to Eugene in 2020 when construction of Hayward Field is complete. The former historic track is being completely rebuilt and is scheduled to be ready for Oregon’s outdoor season next year.
