The Ovarian Cancer Research Fund Alliance’s Ovarian Cycle is back for its 15th year in Atlanta, where the fundraiser launched in 2004, eight years before the alliance adopted it as a signature event.

Founded by Bethany Diamond, Ovarian Cycle launched with 40 participants on stationary bikes to honor Debbie Flamm, who died of ovarian cancer at age 43. Last year, more than 1,000 riders at 20 locations nationwide raised more than $730,000 for ovarian cancer research, pushing the total since 2004 over $3.5 million.

The Atlanta ride this year will take place from 1 to 5 p.m. Sunday, April 15, at CycleBar Dunwoody at 4794 Ashford-Dunwoody Road. A portion of the Atlanta proceeds will go the alliance’s Woman to Woman program at the Northside Hospital Cancer Institute, in which cancer survivors provide one-on-one support to gynecologic cancer patients.

“As this exhilarating fundraising event continually expands and gets stronger, it helps bring us closer to the day women will no longer need to be worried about ovarian cancer,” Diamond said. “Since Day 1, Atlantans have set an example with their outstanding dedication to this cause, which is helping fund some remarkable research in the fight against this dreadful disease.”

Atlanta participants may spin for one to four hours and may go solo or split the time as part of a team. DJ Galavance will provide music mixes; spinning instructors will offer motivation. A break is scheduled every hour with snacks and refreshments.

Register at support.ocrfa.org/site/TR?fr_id=1310&pg=entry. The fee is $50 (free for ovarian cancer survivors), and each rider is asked to raise at least $500. Virtual riders, who support the cause but don’t attend the April 15 event, also can sign up, with the same fee and fundraising goal.
