The friends paid £60,000 for One For Arthur
Belinda McClung and Deborah Thomson paid £60,000 for One For Arthur and registered their ownership as Two Golf Widows three years ago.
Their investment came in trumps yesterday when it went on to finish the gruelling race on the top landing the pair £600,000.
Mrs McClung, from Ancrum, in the Scottish Borders, her “race horse partner” Ms Thomson, from Gullane, East Lothian, watched the eight-year-old, trained by Lucinda Russell and ridden by Derek Fox, gallop to victory ahead of 39 other runners.
It's unbelievable. I can't believe it
Some 21 of the horses did not finish the race but all of them were reported to be safe.
The jockey, who only returned to action from injury earlier in the week, said: "It's unbelievable. I can't believe it. He just jumped so well, even though he was a long way back. He never missed a fence, within reason. He was unbelievable.”
And Ms Russell, who is only the fourth woman to train the National winner, added: "He's done us proud, he's done Scotland proud and he's done everyone at the yard proud.”
The win landed the pair £600,000
Speaking ahead of the race, One For Arthur’s owners described the horse as a “great big softie”.
Mrs McClung, 45, said: “Getting the horse was all a bit of a tongue in cheek.
