Texas team rallies for medical research
Mauricio and Jennifer Sampayo are a husband-and-wife team from South Texas competing under the Black Flag Sarcoma banner — a motorsports initiative founded by the Spence family to raise awareness and funding for synovial sarcoma research.
The cause is personal. Their nephew, Callan Spence, continues to fight this rare and aggressive cancer with the same relentless drive he brings to the track. And that drive is considerable.
Callan is an accomplished racing driver who set and reset the Unlimited Class track record at COTA’s Super Lap Battle in a 1,000-horsepower Lotus Exige, and most recently delivered a podium sweep at MSR Houston’s NASA Texas event — breaking the Time Trial record both days with a 1:30 lap time while his father Chas swept the GT Class. The team also claimed a 3rd place National Championship A-Class finish in a 15-hour endurance race, overcoming significant electrical issues on day one.
The Spence Family Synovial Sarcoma Fund has raised millions of dollars supporting research and treatments including TumorGlow, a groundbreaking imaging technology in development at Penn Medicine.
When Mauricio and Jennifer take the stages in Newfoundland, every mile is run in Callan’s name — and in the name of every patient still in the fight.
Motorsport Experience
Mauricio brings four years of track experience to the cockpit, including HPDE events at Circuit of the Americas and a run in the 2025 Carrera Panamericana Sport Tour — one of the world’s most demanding road events.
Jennifer came to motorsport through that shared journey and never looked back. She has embraced every opportunity to be in the right seat as co-driver, and has taken the wheel herself whenever the chance has presented itself.
Tackling Targa for Callan
Targa Newfoundland marks their first major rally on Canadian soil — and after the roads of Mexico, they arrive more than ready.
For this team, crossing the finish line in Newfoundland is the mission. Every stage completed is another lap logged for synovial sarcoma awareness, and another opportunity to carry Callan’s story to a new audience.
“Targa Newfoundland is one of the last great road rallies in North America — raw, demanding, and historic,” said the Sampayos. “It asks everything of a driver and co-driver: precision, trust, endurance, and composure under pressure. Those are the same qualities it takes to fight cancer.”
The Sampayos chose Targa because the mission deserves a stage worthy of it.
A Porsche with Carrera Panamericana pedigree
The 2021 Porsche 911 Carrera 4S Cabriolet the Sampayos will pilot in Newfoundland has already proven itself on some of the world’s most demanding roads, having run the Carrera Panamericana through the mountains and highways of Mexico. It now wears the Black Flag Sarcoma livery — a Porsche built for performance repurposed as a rolling tribute to a young man who refuses to let cancer define him.
Callan Spence was first diagnosed at 16, declared cancer-free, faced a recurrence, and has kept racing forward every step of the way. So has this team.
