With Krista Stangel out of the girls race, Joseph's Lena Moro was able to take advantage of the course, crossing the tape in first place with a time of 24:09.
Moro was aware of the big hill on the coarse and wasn't bothered by it because she prepared for them all week.
"I kept myself relaxed by singing all of the way. It was like a jukebox in my head," Moro said.
Placing second was Wallowa's Caitlin Turner in 24:40, followed closely by teammates Shannon Buck, Monique McKenzie and Victoria Silveira, who placed third, fourth, and fifth, respectively.
Stangel, who decided not to compete in the girls race, ran with the boys and crossed the tape with a time of 19:46, good enough for second, even though she was not awarded any team points and the race was counted as unofficial.
Wallowa's girls team took first place and was the only school to officially field a complete girl's team.
D.J. Lincoln of Enterprise said he felt he couldn't have ran the race he did without Joseph's Kyle Clough pacing him the first half of the race and Enterprise's Stangel in the second part of race. Lincoln took the boys race in 19:39.
Second place went to Wallowa's Tanner Beglau, who ran the race in 19:48, and improved on his time from last week's race by 11 seconds. Elgin's Wil Burgess took third place with a time of 20:14. Enterprise's Matthew Hurley crossed the tape, taking fourth place, and close behind was teammate Patrick Baird, finishing fifth.
The team title for the boys went to Enterprise, which ended the day with 25 points. Second place went to host school Wallowa, with 35 points.
