Layne Riggs captures NASCAR CRAFTSMAN Truck Series victory at Naval Base Coronado in milestone moment for Mattermost, Front Row Motorsports, and NASCAR

SAN DIEGO, June 25, 2026 /PRNewswire-PRWeb/ — Mattermost, the leading platform for secure, mission-critical collaboration, celebrated a landmark victory as Layne Riggs drove the No. 34 Mattermost Ford F-150 to win the NASCAR CRAFTSMAN Truck Series Navy 250 at Naval Base Coronado on June 19. The win came in the first Truck Series race ever held on an active military base and the first NASCAR race ever contested on an active U.S. military base.

Riggs secured the victory in dramatic fashion on the final overtime lap of the 250-mile event, applying pressure late before taking the lead in the closing turns of the 3.4-mile, 16-turn street course. The win marked Riggs’ fourth victory of the 2026 season and continued his unbeaten record on street courses this year.

Mattermost served as the primary sponsor for Riggs’ No. 34 Front Row Motorsports Ford throughout the historic NASCAR San Diego Weekend, with branding featured on the truck, pit box, and Riggs’ firesuit. The sponsorship aligned with Navy Community Day and the 250th anniversary of the United States Navy, underscoring Mattermost’s longstanding commitment to supporting national security and other mission-critical organizations.

“Watching the Mattermost truck win in such a historic setting was an incredible moment,” said Leigh Dow, Chief Marketing Officer at Mattermost. “This was more than a race sponsorship. It was a powerful reflection of the environments Mattermost was built to serve — high-stakes, mission-critical operations where precision, resilience, and secure teamwork matter most. To be part of the first NASCAR race ever held on an active U.S. military base, and to come away with the win, makes this moment especially meaningful.”

The Navy 250 opened the inaugural NASCAR San Diego Weekend at Naval Base Coronado, one of the most significant new event settings in the sport’s modern era. The race featured heavy competition throughout, with multiple lead changes, late-race cautions, and an overtime finish before Riggs emerged in Victory Lane.

The weekend provided Mattermost with a distinctive platform to engage customers, partners, and guests through premium Turn 11 trackside hospitality while honoring military service members during one of the most unique events on the 2026 NASCAR calendar. For Mattermost, whose platform supports secure operations for defense and public sector teams, the setting at Naval Base Coronado reinforced the company’s connection to the national security community.

“Front Row Motorsports was proud to have Mattermost on board for this historic weekend, and it was incredibly rewarding to deliver a win in such a significant event,” said Jerry Freeze, General Manager of Front Row Motorsports. “This race was monumental for the sport, and Mattermost was the right partner for a venue and audience that represent service, performance, and mission focus.”

Riggs’ victory gives Mattermost a milestone debut in NASCAR: sponsorship of the winning truck in the first Truck Series race ever run on an active military base, and the first NASCAR race ever held on an active U.S. military installation.
