World Athletics U20 opens in Eugene amid unhealthy air

World Athletics began its U20 Championships at Hayward Field in Eugene, Oregon, on August 5 while air quality in the area was rated “Unhealthy,” according to KLCC. The five-day meet opened under smoky conditions linked to a regional air advisory, even as athletes from around the world started competition at one of track’s best-known venues. World Athletics says more than 1,800 athletes from 147 member federations are entered in the championships, which run through August 9. KLCC reported that competition proceeded Wednesday morning despite the air readings, and local station KEZI said Lane County had been under an air quality advisory tied to wildfire smoke, with officials warning conditions could affect athletes and spectators until smoke was expected to clear Friday. The opening-day backdrop put a youth global championship and regional weather risk into the same frame at the start of the meet.

KLCC reported on August 5 that the championships were “up and running” even with air quality squarely in the “Unhealthy” range. KEZI reported a day earlier that Lane County officials had issued an advisory because of wildfire smoke and said the smoke was expected to clear by Friday.
