"Catherine and I have heard the wonderful news about your success today - many, many congratulations.
"We know it was not easy, but you have today become true record holders as the first ever disability team to complete what is one of the world's toughest challenges.
"What you have achieved was a triumph of perseverance and teamwork, and you have shown the world what true courage looks like.
"We hope you get some rest now and, please, no driving like that on our roads when you're back!"
