EUGENE, Ore. – After three weeks of training in Sunriver, the Oregon cross country teams return to action for the Washington Invitational Friday afternoon at Jefferson Park in Seattle, Wash.

The men's race features four of the nation's top 12 teams - No. 2 Stanford, No. 5 Oregon, No. 11 UCLA and No. 12 Brigham Young, along with Portland and host Washington, who are also receiving votes.

The women have No. 4 Stanford and No. 5 Oregon headlining, but No. 15 Washington and No. 23 BYU should not be overlooked.

For the men, the meet at Jefferson Park could mark the Oregon debuts of talented freshmen Matthew Maton and Tanner Anderson , as well as Georgetown transfer Ryan Gil . Sophomore Blake Haney may also run for the Ducks for the first time this fall.

The women return five of the six runners who helped the Ducks win the Washington Invitational a year ago. Frida Berge finished eighth and Molly Grabill was ninth, with Maggie Schmaedick (13th), Alli Cash (14th) and Brianna Nerud (15th) close behind.

Grabill, Schmaedick and Abbey Leonardi are set to open up for the first time this fall, while the Washington meet will also mark the Oregon debut for Australia's Jessica Hull .

While much of the pre-race attention will go to newcomers Maton, Anderson, Gil and Hull, two-time defending NCAA championwill be running in Seattle for the first time in cross country. Cheserek has won nine of his last 10 starts, as well as 10 of 13 career starts overall. The Washington race will be the next step as the Ducks look to build a wealth of depth behind Cheserek against a competitive field. This will be the men's team's first regular season meet in Seattle since the 2003 Sundodger Invitational.

The women won this event in 2014 with the Ducks' posting an impressive :21 spread between their first and sixth place runners. The Washington Invitational was the first of a number of races that saw Oregon run well as a pack throughout the season.

SCORING

The place of the first five finishers counts toward the team score. The next two runners may displace runners from opposing teams. First place is worth one point, second place two points, etc. Low score wins.

The Jefferson Park Course consists of multiple two kilometer loops on flat fairways crossing some cart paths. The course was the site of the 2010 Pac-10 Championships, the USATF Club Nationals, and the NCAA West Regional Championships in 2012.
