Zelda Williams paid tribute to her father Robin Williams at the 2015 Noble Awards, where she presented the Activism in Sports award to the Challenged Athletes Foundation, a non-profit group the actor supported, which provides prosthetics to disabled athletes.

The Oscar winner, an avid cyclist, took part in the organization's annual San Diego Triathlon Challenge for more than a decade.

"Watching my dad get on a bike was like watching a penguin spread its wings and take flight," Zelda, 25, said at the Noble Awards. "He'd take off at inhuman speed, a smile on his face and never look back."

Rudy Garcia-Tolson, a 26-year-old double above knee amputee and a Paralympic swimmer, was part of the actor's Team Braveheart relay team at the triathlon. He was just a boy when he met Williams. The actor died at age 63 last year.

Garcia-Tolson posted a photo of the award on his Twitter page.

Zelda had recently opened up about her father's death for the first time, in a Today show interview, in which she shared memories of the actor and spoke about his work with the CAF Foundation.

Late Fast & Furious actor Paul Walker, who died at age 40 in 2013, was also honored for his work with Reach Out Worldwide, a nonprofit foundation he founded that helps mobilize aid workers when natural disasters strike.

His brothers Cody Walker, 26, who now serves as the group's CEO, and Caleb Walker, 37, joined the actor's Fast & Furious co-stars Michelle Rodriguez and Tyrese Gibson on stage to pay tribute to the actor.

Nikki Reed, a longtime animal activist, was recognized for her work with the Wildlife Waystation, a non-profit animal sanctuary, and the Ian Somerhalder Foundation, her fiancéIan Somerhalders organization. The two attended the event together.
