Oregon concludes the regular season by hosting the Oregon Twilight meet on Friday at 4:15 p.m. at Historic Hayward Field. The Ducks will pay tribute to a remarkable group of 20 seniors who have brought Oregon's programs back to national prominence by winning Pac-10 and NCAA championships and earning dozens of All-America awards. In addition to the traditional senior ceremony, this year's Twilight meet will also feature an extraordinary number of additional attractions. Among them:

* Track and field alumni reunion; more than 100 alums are expected to attend.

* Actor Sam Elliott will be on hand in person to introduce a new documentary about Bill Bowerman, titled "Builderman" that will be shown publicly for the first time Friday night. Elliott, a Brownsville, Ore., resident famous for his big screen roles in Tombstome andThe Big Lebowski, brings his distinctive voice as the narrator for the new film.

* The Twilight meet's tradition of reaching out to the younger generation of fans continues with the kids' half-lapper and middle school miles.

* Greek Relays. Eight fraternities and five sororities will vie for the title of fastest house on campus in 4x100 meter relays.

This weekend also marks the opening of the championship season with the Pac-10 heptathlon and decathlon taking place in Tucson, Ariz. Competition starts at 4 p.m. on Friday and 3 p.m. Saturday at Drachman Stadium.

FEATURED SECTIONS
While the Twilight meet begins at 4:15, the featured sections coincide with the beginning of the free webcast at 5:30. That's when the men's 100 meters goes off in a football heavy race of LaMichael James, Kenjon Barner and Dior Mathis of Oregon, Markus Wheaton and Keynan Parker of Oregon State and former Duck Jordan Kent. Also look for exciting fields in the men's 3,000 meters, 110 meter hurdles, high jump, long jump, hammer and javelin, and the women's 800 and 1,500 meters, hammer and javelin. And of course the distance medley relay.

ON THE TRACK
With all the extracurricular activities going on at the Twilight meet, it would be almost easy to forget the action going on inside the oval. That would be a mistake. To wit: the final event of the night is a rare distance medley relay between Oregon and the Oregon Track Club Elite. There are also a number of elite athletes entered in the meet as many have their eyes on the USA Track & Field Championships at the end of June. Among the more notable men's names are the OTC Elite's Ashton Eaton, Stephen Pifer, Ben Bruce and Cyrus Hostetler, as well as Jordan Kent. For the women, it's Maggie Vessey (New Balance), Kim Kreiner, Latavia Thomas and Erin Donohue (Nike), Britney Henry and Brie Felnagle (adidas), Loree Smith (New York Athletic Club) and OTC Elite's Bridget Franek. That's not to mention all the Oregon entries, like Jamesha Youngblood, Anne Kesselring, Becca Friday, Laura Roesler, Claire Michel, Melissa Gergel, Mandy White, Amber Purvis, English Gardner, LaMichael James, Dior Mathis, Kenjon Barner, Elijah Greer, Boru Guyota, Eric Hersey, Brian Schaudt, Jordan Stray and Alex Wolff.

KIDS' HALF-LAPPER
All kids aged 5-12 are welcome to participate in the Half-Lapper, and need only to sign up at Hayward Field the night of the meet.

TWILIGHT MAGIC
The last three Twilight meets have produced some pretty memorable moments. Last year, Matthew Centrowitz and Mac Fleet became the 29th and 30 Ducks to run under four minutes in the mile. The football team also staged an exhibition 60 meters, which was won in impressive fashion by freshman cornerback Dior Mathis in 6.87. In 2009, the Ducks set the collegiate record in the 4xMile relay (16:03.24) as fans lined the track to spur on the Men of Oregon, while Jesse Williams cleared 7-8 in the high jump. At the 2008 Twilight, then-presidential hopeful Barack Obama worked his way around the East and West Grandstands before Andrew Wheating ripped off a meet-record 3:38.60 to win the 1,500 meters.

THE SENIORS
The University of Oregon will recognize an exceptional group of 20 senior track and field student-athletes with an on-field ceremony during the Twilight Meet. Combined, they have 11 NCAA event titles, nine individual Pac-10 crowns and a whopping 44 All-America certificates. They have also won 15 Pac-10 all-academic honors over the past three years.

The nine senior women are all Pac-10 qualifiers and eight of the nine are Pac-10 scorers. They have been part of Oregon teams that have won back-to-back NCAA Indoor Track & Field championships in 2010 and 2011, as well as back-to-back Pac-10 titles in 2009 and 2010.
