The Super Bowl 50 champion is turning his cycling hobby into an opportunity to raise money for a cause close to his heart.

Former Denver Broncos offensive lineman Tyler Polumbus will cycle 100 miles on September 19 to benefit the Colorado Ovarian Cancer Alliance and the battle against ovarian cancer.

Polumbus created the event in honor of his mom, Nancy, who battled the disease for six years before passing away in April. 

"Ovarian cancer is deadly and many women don’t know they have it until it’s advanced and difficult to treat," said Polumbus. "My mother wasn’t any different. She had no idea she wasn’t healthy until her stomach became bloated and she gained about 15 pounds in a very short period. After watching my mom battle with ovarian cancer, I believe this must change before others lose their mothers, wives, sisters or daughters." 

Polumbus will pedal around Empower Field at Mile High to complete 100 total miles, an estimated 166 laps. He said he is unsure how many hours it will take him to complete the challenge but hopes the public will support his effort through donations. Donors can choose to make a flat donation or a per-mile pledge and can earn prizes from a limited-edition t-shirt to a Pedal With Polumbus cycling jersey.

The event surpassed its initial goal of raising $20,000 in August and has set a new goal of $25,000.

More than 20,000 women are diagnosed with ovarian cancer across the country each year. It is frequently misdiagnosed or caught after it has advanced because symptoms can be vague, like bloating and abdominal pain. The mission of the Colorado Ovarian Cancer Alliance is to promote awareness and early detection of ovarian cancer through advocacy and education and to support those affected by the disease. 

Denver-native Polumbus was a standout athlete at Cherry Creek High School and was a team captain of the Colorado Buffaloes football team before playing in the NFL for eight seasons. He retired from the NFL after winning Super Bowl 50 with the Broncos in 2016. 

Following his pro-football career, Polumbus entered the media and now is a host alongside Darren "D-Mac" McKee on 104.3 The Fan's afternoon sports talk show The Drive.
