Democrat Rachael Scdoris-Salerno will challenge Republican Rep. Greg Walden to represent Oregon’s 2nd District in 2018.

Scdoris-Salerno, 32, is most well-known for competing in four Iditarod sled-dog races and as a tandem cyclist at the Paralympics twice. She is legally blind due to a congenital disorder called achromatopsia. She and her husband own a sled dog tour business in Bend, Ore.

Inside Elections with Nathan L. Gonzales rates the district as Safe Republican.

Scdoris-Salerno said that running for office hadn’t been on her mind until the passage of the Republican health care bill in the House.

“As a person with a pre-existing condition it was nearly impossible for me to get insurance as a young adult,” she said. “With Obamacare I was finally able to get coverage. Now the powers that be in Washington are working to dismantle that.”
