Shelby Daniele — a college track star who broke records at California Polytechnic State University — has passed away according to a statement from the university.

The university’s athletic department released a statement via Instagram Friday … saying they were profoundly sad to hear about the former athlete’s passing who they say had a remarkable heart. Cal Poly did not reveal a cause of death.

Daniele — who received both a bachelor’s and a master’s degree at the school — served as Cal Poly’s team captain and was a six-time All-Big West honoree and a two-time Big West champion.

Tragically, it appears Daniele had just received her master’s in agriculture from the school back in June … posing alongside family members with a huge smile on her face.

According to her LinkedIn, Daniele wanted to “improve the environment and give back to our society” … which is why she chose to focus on agriculture.

Shelby was 23.
