Riverside High School opened in the fall of 1959, and, in 1966, the school had its first ever WPIAL champion: Chuck Kotuby.

Starting in 1964, when Chuck began his sophomore year at Riverside he competed in cross country, basketball, and track. In the fall of 1966, he won the WPIAL Class B cross country championship and helped his team to a WPIAL co-championship and runner up position at the PIAA championships. In the spring of 1967, Chuck led the Riverside track team to its first ever WPIAL team championship, winning the track and field team title. Chuck was WPIAL champion in the mile run and went on to be Riverside's first ever PIAA champion when he won the Class B mile run.

Chuck attended West Liberty University (1968-71), where he received WVIAC all-conference honors in cross country and track and field, and graduated with a degree in health and physical education.

Chuck went on to coach football, basketball, and track at River High school in Hannibal, Ohio (1972-74) and the Ellwood City school district (1975-79). In 1981, Chuck started the Riverside youth soccer league, where he coached for eight years. In 1989, Chuck organized the first varsity soccer program at Riverside High School. In 1993, Chuck served as assistant soccer coach and helped lead Riverside to its first ever soccer section championship.

In 1996, Chuck was hired as Riverside's boys' track coach and from 1996 to 2001 he compiled a section record of 26-5, with three section championships. In 2004, Chuck was hired as Riverside Middle School's physical education teacher and rehired as the boys' track coach after two years off.

Over the past 20 years, Chuck coached the Riverside track team to an overall section record of 115-5 and an overall WPIAL record of 138-24. Even more impressively, from 2005 to 2018, Chuck's boys track teams did not lose a section meet, and, over the past 14 years have compiled a section record of 98-0. During that time, Chuck's teams won five WPIAL championships (2008, 2009, 2011, 2017, and 2018), which is tied with the most WPIAL team titles in Class AA team history. Chuck's boys track teams were also runner-up in 2010, 2013 and 2014. Chuck's coaching has produced numerous state medalists and six individual PIAA champions.

In January 2019, the Riverside school board voted to name the track at Memorial Stadium in honor of Chuck for his years of service and success.
