The family of the late Race Across the World contestant Sam Gardiner have issued a message of thanks for the love and support they have received following their son's death.
They have also thanked people for donations to a fundraising campaign set up in his memory.
The 24-year-old, who competed in the BBC One series alongside his mother Jo in 2020, died following a car crash last month.
A JustGiving page launched in his memory by his family, in aid of National FASD (Fetal Alcohol Spectrum Disorder) in the UK, has so far raised more than £10,000.
Sam Gardiner's mother Jo said: "We have been overwhelmed by the tens of thousands of messages of love and support on social media and in comments to press reporting.
"We would like to thank the BBC, Studio Lambert and everyone at Race Across the World production, fellow contestants and fans of the show for all their support at this terrible time. It has been very comforting to know that Sam touched so many people.
"I have been particularly moved by all the messages that Sam was an inspiration to many who have been impacted by Fetal Alcohol Spectrum Disorder.
"We adopted Sam and he was diagnosed with FASD. As viewers of season two will recall, this was a big challenge both for Sam and for us as his parents.
"National FASD helped us on that journey. If some good comes of this tragedy, it will be that FASD is better understood."
Sam Gardiner was driving a white Volkswagen Golf R Estate when it came off the road and rolled before landing on its side.
The accident happened on the UK's A34 in Gatley, near Cheadle, on Monday 26 May.
Sam Gardiner died on 29 May from his injuries, his family said last week.
His father Andrew said: "When the news broke last week, friends asked how they could help.
"After some thought, I decided to set up a JustGiving page to raise money for National FASD in memory of Sam. The page is called Sam Gardiner; Super Human.
"I set the target at £500 thinking a few friends might be generous enough to make a donation. So far, it's raised 20 times that. It's very humbling to see the RATW family rally to this worthy cause."
The UK's National Organisation for FASD says on its official website that it "provides support to people with Fetal Alcohol Spectrum Disorder, their families and communities, campaigns to raise public awareness, and promotes relevant policies and practices".
The website also describes FASD as resulting "when prenatal alcohol exposure affects the developing brain and body".
It says: "FASD is a spectrum. Each person with FASD is affected differently.
"While more than 400 conditions can co-occur, FASD is at its core a lifelong neurodevelopmental condition. All people with FASD have many strengths. Early diagnosis and appropriate support are essential, especially for executive functioning."
A message on the official National FASD Instagram account said: "Sam lived his life full of love, exuberance and adventure as seen on BBC's Race Across the World.
"National FASD is both humbled and honoured to help carry on his legacy via donations coming from hundreds."
A private funeral will be held later this month.
