Races at Freeman Park in Idaho Falls begin at 11 a.m. and run through 2:30 p.m. Here is a look at the field, which includes more than 750 runners:
Individual: Mountain View senior Sam McKinnon was 20 seconds ahead of her nearest competitor with a time of 17 minutes, 55.1 seconds in the District Three meet. Shes bound to get competition from two-time champion Emily Hamlin of Boise, plus last years runner-up Josie Brown of Coeur dAlene and third-place finisher Makayla Malaspina of Vallivue.
Team: Coeur dAlene is the favorite after winning by a large margin last season. Boise, which finished third, is coming off a district win.
Individual: Junior Will Eddy of Hillcrest has the best time among entered runners in 15:14.0. District Three champion Andrew Rafla of Timberline is second in 15:18.2, but dont overlook defending champion Dwain Stucker of Meridian, Mountain Views Jared Capell, Capitals Zach Wieberg or Lake Citys Jake Finney.
Team: Rocky Mountain won last season, but took third at this years district meet behind Mountain View and Capital. Hillcrest is a threat.
Individual: Rachel McGovern of Pocatello is the defending champion, but isnt on the roster for state. That opens up the competition to at least two competitors Blackfoots Rachel Cannon and Moscows Katherine Ruck. They are the only 4A females to run under 19 minutes this season.
Team: Bishop Kelly finished sixth last season, but won this years district meet and could be a contender alongside Pocatello and Sandpoint.
Individual: Elijah Armstrong of Pocatello, the two-time defending champion, is the runner to beat. Sandpoints Sam Levora is the only other 4A runner to break the 16-minute barrier this season. Nampas Alberto De Los Reyes is the district champion.
Teams: District Three champion BK should be in the mix to unseat Pocatello, as could a strong outing from Nampa or Jerome.
Individual: Defending champion Olivia Redd of Sugar-Salem has a season-best time of 18:08.3, which is nearly 40 seconds faster than her nearest competitor. Shelleys Cambria Hassell is the only other 3A runner to run under 19 minutes this season. Harlie Sorrell enters as the District Three champion.
Team: Sugar-Salem can win its second straight title, but will need to hold off Shelley, Snake River and District Three champion Parma.
Individual: Last years champion has graduated, opening the door for runner-up Joseph Van Orden of Snake River. Three other runners Bear Lakes Luke Brogan, Shelleys Austin Stewart and Bear Lakes Garrett Brogan have posted better times than Van Orden this season. Cole Hungate of Homedale is the District Three champion.
Team: Teton won last year, but graduated several top runners. Shelley is among the favorites, but Timberlake could make a run.
Individual: Sierra Manzer of Melba is the favorite as the reigning champion, but two other runners have posted faster times than Manzer this season Kelsey Yamauchi and Jennifer Nielsen of Soda Springs.
Team: Soda Springs won by a large margin last year, and looks to be in contention for a fourth straight title with its top five runners ranked in the top 15 in the state, according to athletic.net. The fight for second through fourth place last year was decided by five points.
Individual: Paul Ryan of the Logos School in Moscow took second last year behind a runner who has graduated. Ryan can expect competition from third-place finisher W. Leif Fredericks of Coeur dAlene Charter. Fredericks is the only runner in the field to eclipse 16 minutes this season. Victory Charters Gabe Fisher is the District Three champion.
Team: Logos won last years title and returns four of its top five runners. Second-place Soda Springs returns its top five runners. Victory Charter is the District Three champion.
