She's achieved great heights in the worlds of business and broadcasting and now Norah Casey is set to conquer one of the world's highest peaks - Mount Kilimanjaro.
The ex-Dragon's Den star (right) has swapped her stilettos for hiking boots to train for the gruelling climb with Irish explorer Pat Falvey, which will be filmed for a documentary.
"I was supposed to climb last week but because our new RTE series [The Million Euro Start-Up] is in post-production I was too busy, so now we're hoping to do it in November. I have to climb a 'peak a week' before then, even if it is a small one," Norah told the Diary. "I've already done Carrauntuohill."
Along with mountaineering, the entrepreneur also runs three times a week to keep as fit as possible.
"I'm a big believer in cardiac exercise. A lot of women my age are addicted to yoga, which I also love, but it's just not enough," she said at the launch of the Irish Heart Foundation's Red Alert campaign.
"Your heart needs a workout everyday."
