“Amazing Race” contestant Donald Anthony St. Claire has died at the age of 87

One of the oldest participants in The Amazing Race, Donald Anthony St. Claire, has died at his home in Northern California at the age of 87, The Post can confirm.

St. Claire, a renowned doctor and “true man of the Renaissance,” passed away on Aug. 31, according to his online obituary. His son Greg told TMZ in a story published Saturday that his death came as a shock – a “heart problem” is suspected.

St. Claire and his wife Mary Jean took part in the sixth season of the long-running CBS reality series. When the show aired in 2004, they were known as the “grandparents” team.

At the time of the competition, Don was 69 and Mary Jean, an interior designer, was 65. They had been married for 20 years at this point, having met while married to others, according to CBS.

In their show bio, the network revealed that the couple once survived a near-death experience when their eight-person boat capsized in the South Pacific, throwing Don onto a coral reef and Mary Jean into the water.

Locals reportedly held a memorial service for them, thinking there was no way they would get out of such a tragedy.

Finally, on The Amazing Race, the pair struggled to keep up with the younger teams. They were eliminated in Germany and finished eighth.

The award-winning winemaker – who was born on January 10, 1935 – is survived by Mary Jean; children Valeri Andres, Donald St. Claire, Jr., Gregory St. Claire and Jeffrey St. Claire; stepchildren Michael Henningsen and Christa Flores; 16 grandchildren and two great-grandchildren.

Off-screen, St. Claire practiced internal medicine in the Palo Alto area for more than 40 years and served on the clinical faculty at Stanford University.

“He was a true animal lover who adored his dogs and a loving father who didn’t hesitate to leave work early on Fridays to pick his kids up from school for trips to Tahoe. He touched everyone who got in his way,” the obituary reads.
