Anna previously shattered the women’s record for running the Southern Upland Way in 2021, completing the 212-mile course from Portpatrick to Cockburnspath in 62 hours and 34 minutes.
Back then, she credited eating stock cubes provided by a support van with helping her to complete the cross-country route.
This time, she said she mixed stock powder with pretzels and took on gels and hydration at 10-mile stopping points along the route.
However, she managed to miss one feeding point, where she had stashed some hydration gels and a note of support from her son.
She said she took inspiration from hero and Barkley Marathon finisher, Jasmine Paris, to overcome the mental blocks on the run.
She said: “It doesn’t matter what the distance is, about 70 or 80% of the way through, it is going to feel really hard because you’ve done the hardest bit, you are getting tired, but there is still a long way to go.
“In a way, I just embraced it. There’s a lot of really, really good ultra-runners out there, who talk about the psychology of getting into this pain cave and just knowing that and almost looking forward to it.
“Someone like Jasmine Paris, her saying ‘just watch me’ before she did the Barkley Marathons, I found that very humbling.”
