3000 Miles to a Cure
In October 2012, after her sister was diagnosed with Stage IV brain cancer, Parker helped found 3000 Miles to a Cure, a brain cancer research funding organization with a goal of raising 1 million dollars to support brain cancer research.
As part of 3000 Miles to Cure's fundraising efforts, Parker participated in Race Across America, the 3000 mile cross-country bike race, in 2013. Parker won the race, despite facing setbacks early on. 612 miles into the 3000 mile race, her follow vehicle was rear-ended by a texting driver outside of Tuba City, Arizona, and several crew members, including Parker's son, suffered minor injuries. In addition, her backup bikes and primary follow vehicle were destroyed, and Parker withdrew from the race. However, after a 24-hour break, Parker resolved to continue the 3000 mile ride, believing that she would be disqualified for missing a time cut-off. Upon resuming her ride, the Race Across America organization forgave the time cutoff that would have disqualified Parker, and allowed her to re-enter the ride as an official racer. After returning to the race, Parker quickly climbed the women's field, performing what RAAM commentator David Towle called "one of the greatest rides in Race Across America history". Helped by six-time RAAM winner Seana Hogan's early withdrawal, Parker finished first in the women's field with a time of 11 days, 20 hours, and 54 minutes.
