A two-time All-American, Rizika became the first Cornellian to earn MAISA Sailor Athlete of the Year when she was honored as a senior. An ICSA honorable mention All-America skipper as a junior in 2019 and a first-teamer as a senior in 2020, she was an all-conference first-team pick both years. She was part of two straight MAISA Fall conference championships. Rizika was the team's top finisher at the Faye Bennett Women's Singlehandeds as a junior, placing seventh overall. She sailed the Big Red to the Sperry Women's Finals with her efforts in A division, posting six top five efforts, including a win in the event's final race. Rizika also competed in fall conference championships at the MAISA Women's and War Memorial and in the spring at the Prosser Trophy, MAISA Women's national qualifier and the America Trophy. She earned second-team All-MAISA as a sophomore, serving as skipper in A Division for the Big Red at the Sperry Women's Western Semifinals and National Finals as Cornell placed seventh nationally. She also helped the team to an eighth-place finish at the MAISA Women's to qualify the Big Red for nationals. Rizika placed 13th at the Faye Bennett Women's Singlehanded Championship in the fall. She skippered B division at the Sperry Women's National Semifinal, posting seven top 10 finishes in nine races, and suited up at the MAISA Women's Fall, MAISA Women's Spring and America Trophy conference championships. Her spring senior season was ended prematurely due to the coronavirus pandemic.
