A typical weekend in Denver doesn’t usually involve a polo tournament. But for the past 30 years, Denver Active 20-30 Children’s Foundation has hosted the country’s largest charitable polo event right here in the Mile High City. And they’re not horsing around—last year, the organization raised more than $1 million to give back to local at-risk and disadvantaged youth.

Active 20-30 is a national organization made up of men and women in their 20s and 30s who want to help children in their communities through fundraising and hands-on support. The Denver chapter was started in 1987 by five young men, and is still an all-male group. “The mission was to get young people engaged early in making a positive impact in their community,” says Caleb Hester, DA 20-30 president.

One-hundred percent of the money raised at the annual Denver Polo Classic and other events hosted throughout the year supports local nonprofits, which are chosen through DA 20-30’s grant review process. Last year, the committee reviewed 140 applications, and they were able to fund between 50 and 60 proposals. Local organizations can apply for funding from May 15 to July 31.

Members of DA 20-30 get involved in the community in many ways, from sponsoring students through the Colorado I Have A Dream Foundation, an organization that aims to raise graduations rates by supporting students throughout their education, to consulting with local nonprofits to provide advice and assistance. But the largest community impact comes from the Denver Polo Classic, the organization’s biggest fundraiser, which Hester says is expected to attract around 3,500 attendees this weekend.

The event kicks off on Friday night with the Tempus Jets Black Tie Dinner, followed by a live auction and tunes from the popular Colorado horn band Funkiphino. The polo tournament starts the next morning with two qualifying matches, along with family-friendly festivities that include a Kid’s Tent with face painting, balloons, and more. If polo isn’t your sport, don’t miss as canines participate in an obstacle course relay between matches. On Sunday, enjoy the championship polo match and celebrate with food and drinks from local vendors.

“If you’re looking to experience a fun nonprofit event, to learn a little bit more about polo, and to be able to say you are a part of a $1 million impact in the community, we’d love to have you there,” Hester says.
