Love at first spike!

Professional beach volleyball player and The Amazing Race finalist Maddison McKibbin married Chelsea Hayes on Saturday in Mexico.

For the "extremely casual" nuptials, the groom wore a white linen shirt and made the playlist himself. Guests were greeted by a mariachi band playing, and the couple opted for no assigned seating and a buffet of Mexican food, including popsicles rather than a wedding cake for dessert.

"It's more about people getting together, seeing old friends and having a good time," McKibbin tells PEOPLE.

The Amazing Race winners Will Jardell and James Wallington, who appeared on season 32 of the CBS reality show with McKibbin and his brother Riley, also attended.

The destination wedding was in one of McKibbin's favorite "staycation" spots, only a few hours drive from his home in California, and was a days-long celebration, complete with wine tasting and relaxing at the beach.

McKibbin met his now-wife when she was his trainer at Mamba Sports Academy in Thousand Oaks, California. He proposed in October 2020 during a hike in San Simeon, getting down on one knee on the bluffs overlooking the water.

"The words didn't come out as smooth as I wished they would, but that's how it happened," McKibbin says.

He then surprised Chelsea by having about 30 friends and family members back at their campsite to celebrate the engagement with them.

The McKibbins also recently celebrated a new family member: Maddison's brother Riley and his girlfriend, professional indoor volleyball player Carli Lloyd, recently welcomed a daughter named Storm.

"It's so much fun to be an uncle," Maddison says. "We've had a lot of stress lately and for some reason, going over there and hanging out with my niece is soothing. It makes you put things in perspective."
