It's been a busy offseason for DeMarcus Ware.

The veteran pass-rusher signed a three-year, $30 million deal with the Denver Broncos earlier this offseason and participated in the Mint 400 race in Nevada.

More recently, Ware packed a moving box and ran from Dallas to Denver. Ware is training to participate the Wings for Life World Run in Denver on May 4. The run is dedicated to funding spinal cord injury research, something that hits close to home for Ware.

During a game in 2009, Ware sprained his neck during a play and was immobilized on a stretcher and carted off the field. It was a terrifying moment for Ware. He is now running to support those who suffer from spinal injuries.

"I was briefly paralyzed," Ware said. "You're sitting out there on the field not knowing if your career is over or if you'll be playing football again. So for a brief moment—not a lifetime—I knew what that person in a wheelchair or a person who is disabled felt. So for me to be able to get up and walk off the field and still play now, I have an opportunity to let them know there are people out there who care. That's why I'm running."

According to a press release sent out by Red Bull, the outstanding feature of the Wings for Life World Run is that the moving finish line will be pursuing the racers from behind instead of the racers running towards a set finish line. Exactly 30 minutes after the runners set off at some of the most spectacular locations around the world, official 'Catcher Cars' will set off behind the packs in pursuit of the runners. When a Catcher Car passes a runner, their race is over. The last man and last woman running will be declared the winners.

This year, races will take place in three U.S. locations: Denver, Colo., Sunrise, Fla., and Santa Clarita, Calif. Runners can register for the event at www.wingsforlifeworldrun.com.
