OKLAHOMA CITY - Superhero Weekend in Downtown Oklahoma City's Boathouse District kicked off Friday. 

Kids were able to meet there comic book favorites at Riversport Adventure Park, but they were joined with Oklahoma City's real superheros, our firefighters, police officers and EMSA. 

“As a nonprofit organization, we are trying to raise funds to support our first responder programs here at the boathouse district,” Mike Knopp, executive director of the Oklahoma City Boathouse District, said.

Just this year, Riversport OKC started a program called OKCRespond. It focuses on supporting first responders by offering them fitness and wellness programs free of charge.

Right now, they have more than 500 members, but are looking to expand.

“ We’re taking all of the resources that we have here, like the whitewater center, our high performance center, and providing that to our first responders,” Knopp said

Superheroes weekend also consisted of "The Great Duck Race", where 3,000 rubber ducks were sent down the Riversport Rapids.

Duck sponsorships were 50 dollars, and the proceeds went toward OKCrespond.

“We are an Olympic training site here in Oklahoma City. So we have a high performance center with Olympic hopefuls and we thought we can apply that same focus on supporting our first responders,” Knopp said.

OKCRespond is funded by private donations, so the more they raise, the greater the number of people they can support. You can find more information on Riversport OKC's website.

“What we’re doing today is really showcasing our great first responders, but also you know really showing that they are real life superheroes,” Knopp said.

If you missed today’s festivities, make sure to come out Sunday as they honor first responders and their families with a free lunch cookout. You can preregister for that by clicking here.
