Gabrielle Giffords, rebounding from shooting, does 40-mile bike - Just after she participated in an 11-mile bike ride for charity last year, former U.S. Rep. Gabrielle Giffords decided she could do more.

This year, she and her husband, Mark Kelly, planned to ride 40 miles in El Tour de Tucson, an annual event that draws nearly 10,000 riders and took place Saturday.

Giffords is still recovering from the mass shooting outside a Tucson grocery store on Jan. 8, 2011, that left six dead and 13 injured, including the former congresswoman. Giffords was shot in the head and suffered severe injuries, leaving most of the right side of her body paralyzed. She had to resign her seat in Congress.

But Giffords has been determined to overcome her injuries. She's skydived and traveled the country advocating for stricter gun regulations with Americans for Responsible Solutions, the organization she founded with Kelly.

“My recovery has been full of milestones both big and small, and a big one was getting back on my bike and back to riding around this gorgeous city of ours with friends and family,” Giffords said in a statement to the Associated Press.

Giffords has been training for the long bike ride several times a week over the last year, she said. It hasn't been easy, and she took a tough tumble in the spring.

I want everyone recovering from an injury or setback to know that determination and a little grit can take you a long, long way.

“But I kept working hard, and I'm ready. Mark and I are so excited to be back riding in the El Tour again, and to join with so many of our fellow Tucsonans and with people from around the world for a ride around our community. I want everyone recovering from an injury or setback to know that determination and a little grit can take you a long, long way, and help you achieve things you might have thought were impossible.”

Giffords planned to ride in a retrofitted recumbent bike and Kelly a regular one. The organizers of El Tour dedicated the event to Giffords and Kelly, a retired astronaut.

Giffords showed enthusiasm for the race on her Twitter account.

“Training's done. Bike's ready. @iamspecialized gear is laid out. I'm ready to tackle 40 miles in @tourdetucson!” she tweeted Friday.
