INDIANA — Two university students completed a 4,600-mile bicycle trek from Western Pennsylvania to Alaska aimed at raising awareness about cancer.

Twenty-year-old Daniel Esten and 23-year-old Michael Frederick, both students at Indiana (Pa.) University, completed their journey in 79 days. They began their journey on May 28 and reached Anchorage, Alaska, on Aug. 14. They biked between 70 and 80 miles each day.

On Tuesday, they returned to Indiana, a town about 60 miles northeast of Pittsburgh.

Esten and Frederick have both had relatives impacted by cancer. They thought their trek could help raise awareness for the American Cancer Society.
