Over the weekend, the nation's premier cross country programs had one last tune-up before things get even more serious next week at NCAA Regionals. 

From upsets out west to new champions on the East Coast, there were prominent performances all around. 

Here are four of the biggest stories of conference championship weekend.

Exactly two weeks removed from the Nuttycombe Invitational, the Big 10 met back up in Madison, Wisconsin, for the Big 10 Championships. 

No surprise, the Wisconsin men completely stole the show ... as they often do. Led by now three-time defending Big 10 champion Bob Liking, the Badgers put their top six runners within the top 10, going 1-2-4-5-7-10. Liking was the lone man under 24:00, winning by nine seconds over teammate Jackson Sharp in 23:57. 

This marked the third straight year that a pair of Wisconsin men went 1-2 and back-to-back years for Liking and Sharp. 

Michigan's Tom Brady broke up the Wisconsin quartet in third, but Evan Bishop and Adam Spencer were hot on his tail, running 24:23.3 and 24:26.0, respectively, to round out the top five. Rowen Ellenberg brought the team's scoring to a close, clocking 24:30.8. 

With the team's sixth consecutive title, Mick Byrne is now tied for most Big 10 titles of all-time. 

He's even with Martin Smith ('83-'98), both now at 12. Overall, Wisconsin put up just 19 points, while Michigan and Michigan State were second and third with 63 and 86 points, respectively.

Washington Women Upset No. 5 Stanford In Last Pac-12s

In Seattle, final Pac-12 Cross Country Championships were underway, the final in the conference's history -- eight teams are set to join new conference at the beginning of the 2023-2024 academic year. 

Coming into the competition ranked No. 19 in the country, the the Washington women took down the fifth-ranked Stanford Cardinal to claim its first conference title since 2009, and its fourth overall. 

Sophie O'Sullivan led the way for the Huskies with a PR of 19:33.8 that earned her a sixth-place finish. Teammates Chloe Foerster and Julia David-Smith were right behind in seventh and 10th, crossing in 19:34.2 and 19:37.0, respectively.  

India Weir (19:49.7) and Tori Herman (19:57.6) capped the scoring for Washington, both breaking 20:00 while finishing 14th and 21st. The team battle was practically as close as it could be, with Washington nipping the Cardinal by two points, 58-60. 

Despite Stanford putting two in front of O'Sullivan, it was the Huskies' spread of 24 seconds that gave Maurica Powell's squad just enough to finish atop the conference in its last showdown.

UNC Knocks Off Syracuse For Its First ACC Title Since 1985

The last time the Tar Heels won an ACC title in cross country, the original Back to the Future was the must-see movie in theaters and the United States was still in the midst of the Cold War. 

Long-story short, it's been a while. 

After decades of watching the ACC progress, the North Carolina men finally earned the statement win they had been searching for. Down South in Tallahassee, Parker Wolfe led his UNC unit to its first title in 38 years, with Wolfe winning his first conference title after a string of runner-up finishes. 

Aided by three other teammates in the top nine, the Tar Heels comfortably held off Syracuse and Virginia (49-65-77). Alex Phillip (23:14.2), Ethan Strand (23:20.4) and Jake Gebhardt (23:26.6) went 4-6-9, with Colton Sands placing 29th in 23:59.3. 

This will most definitely shake up the national rankings, as Syracuse was ranked fourth in the country heading into Friday, while North Carolina was sitting in 11th.

Another race, another Parker Valby masterclass. 

After most recently pulling away for the win at Nuttycombe, the reigning 5,000m national champion did it again, winning in 18:37.5, and she pulled away with 2k to go. 

She crossed over half of a minute ahead of runner-up Doris Lemngole of Alabama. This was Valby's second-fastest performance of all-time and her fastest this season. 

Behind her, Flomena Asekol (19:31.9) was fourth, with Amelia Mazza-Downie (19:56.7) followed in eighth. Elise Thorner and Allison Wilson solidified the team title thanks to their 17th and 19th place finishes, just enough to break up the potent Razorback pack. 

Despite their 46-second spread, the Gators were too far ahead to reel in. Florida won its first SEC title since 2012, beating out Arkansas, Tennessee and Alabama.
