The Cal Poly men's team was one of two West Region schools (Washington State) to earn an at-large selection and will be joining automatic qualifiers Stanford and Portland from the region.
The Mustangs selection was propelled by the team's third place finish at Saturday's NCAA West Regional at Stanford.
The Mustangs placed all seven runners in the top 47 with senior Daniel Gonia setting the pace with his ninth place finish, covering the 10k course in a time of 29:28.
The women's team made history with the selection of senior Leanne Fogg and true freshman Meghan Breadmore getting the invitation to compete at the NCAA Championship as individuals.
This marks the first time that an individual or team from the Cal Poly women's program has advanced to the NCAA Division I Championship since the Mustangs made the jump in 1994.
Cal Poly upset a number of schools with its ninth place finish at the regional with the team paced by senior Leanne Fogg's 16th place finish and true freshman Meghan Breadmore's 17th place finish. Fogg covered the 6k course in a time of 20:45 with Breadmore posting a time of 20:47.
The Mustangs were two of four West Regional competitors to receive individual selection.
For the men's team it will be the seventh time that the team has made the trek to the championships and 13th time that a Mustang team or individual has been selected.
