Marathoner Jamie Shinneman and his wife, Amy, of Noblesville, Indiana, USA, are joining the 2026 Sydney Marathon on 30 August.

As usual, Jamie, 53, will be running the regular way, while Amy will be riding a three-wheeled racing wheelchair they call a “duo bike” pushed by him. Amy, 52, was diagnosed in 2018 with Bethlem myopathy, a rare form of muscular dystrophy that causes progressive muscle weakness and affects mobility, CBS News reported. She is wheelchair-bound now and relies on her husband for assistance.

The couple has finished four marathons together since 2019 using the duo bike. The Australian race is part of the eight Abbott World Marathon Majors that the couple are trying to complete. They will also run in the succeeding marathons in London, Tokyo and Cape Town.

“She’s seeing parts of the world she’s never seen before on a trail,” Jamie said of one benefit of their runs, according to CBS News.

Their participation in marathons also serves to inspire others with a disability to go outside of their comfort zones. Raising money, like the $26,000 that the Shinnemans set as a goal to donate to the Muscular Dystrophy Association, isn’t bad either.

Like the Duo Team of Jamie and Amy, Long Island, New York, ballroom dance instructor John Mazzei, 57, also never fails to be noticed and greeted by people because of his unusual way of running.

Currently training for the Boston Marathon, Mazzei’s running style was inspired by Christopher McDougall’s “Born to Run,” he said, according to the New York Post (NYP).

After reading the book about barefoot running, Mazzei gave it a try and liked it. He got used to running sans shoes and socks.

Mazzei has built a fan base after running several marathons barefoot. They honk their horns when they see him running shoeless and yell, “Barefoot John!” the NYP reported.
