An anniversary and an end when Michelin Pilot Challenge takes on Laguna Seca this weekend.

It can be difficult to keep up with on-track action during the StubHub Monterey Sports Car Championship weekend.

While the primary focus will be on the state-of-the-art prototypes and GT cars running for the national sports car title on Sunday, points are also up for grabs in the Mustang Challenge, Lamborghini Super Trofeo and Michelin Pilot Challenge series.

The latter takes on WeatherTech Raceway Laguna Seca on Saturday for what may be the last time, at least for a while. The two-hour race on May 2 is Michelin Pilot Challenge’s only West Coast appearance this year. In 2027, the event moves to Lime Rock Park in Connecticut.

Thomas Merrill, who lives close enough to Laguna Seca to hear the action, returns in the No. 14 Circle H Racing Aston Martin Vantage AMR GT4 Evo along with co-driver David Hampton. But another team is marking an anniversary of importance on and off the track.

This is the 10th year that the No. 19 Stephen Cameron Racing Ford Mustang GT4 has worn the “names” livery representing Racing to End Alzheimer’s. The sponsorship began with the 2017 race at Laguna Seca.

Over the decade, almost 1,000 names have adorned the machine on race weekends. Anyone can honor a friend or family member by donating $250. The sponsor behind Racing to End Alzheimer’s—Los Angeles-based Legistics, a firm providing professional support for the legal market—matches donations. The partnership has raised more than $1.2 million, which goes to the UCLA Alzheimer’s and Dementia Care Program, as well as the Nantz National Alzheimer’s Center.

Jim Nantz, who owns a home in Pebble Beach, detailed his father’s struggle with Alzheimer’s in the book Always By My Side: A Father’s Grace and a Sports Journey Unlike Any Other.

Another Monterey County resident, Nick Galante—who piloted the first Racing to End Alzheimer’s machine in 2017 and now acts as an ambassador for the program—adds the names of his grandmother and aunt to the car each year.

At Laguna Seca, more than 100 names will appear. The Mustang is currently driven by Greg Liefooghe and Sean Quinlan.

The Michelin Pilot Challenge teams have practice sessions at 9:10am and again at 1pm on Friday, May 1 before qualifying starting at 5:40pm that same evening. A total of 45 cars are entered in the race, which rolls on Saturday at 12:45pm.

Last year Jan Heylen and Luca Mars took the checkered flag in the GS class driving the No. 28 RS1 Porsche 718 GT4. Preston Brown and Denis Dupont claimed the TCR crown in the No. 76 Bryan Herta Autosport Hyundai Elantra N.

On Saturday fans will find out who wins the last Michelin Pilot Challenge race at the iconic track, at least for the near future.
