Janet Ross, from Hassendean, and her niece Natalie Macfarlane completed the gruelling 54-mile Caledonian Challenge in 26.12 hours.
Other team members of Team Mac, Andrew and Liz Macfarlane, covered an impressive 30 miles before retiring due to injuries.
The walk started in Spean Bridge at 7am on a glorious summer day, and followed the route of the West Highland Way southwards to Tyndrum via Kinlochleven and the Devil’s Staircase.
The challenge was blessed with beautiful sunshine, with the odd shower and a few midges, hardly detracting from the stunning scenery.
In total 781 individuals set off, either walking or running, and 82 per cent finished.
Janet said: “I loved the day time walking and we just kept plodding on, with frequent food and drink stops.
“The night time between 11pm and 4am was particularly long when we did 16 miles across Rannoch Moor.
“We met some lovely people, and the banter was great with brilliant camaraderie. Snacks, compedes and laughter were exchanged and it all helped the time to pass more quickly.
“Natalie and I found the last ten miles seemed to go on forever, but by then there was no chance of us giving up. Natalie was amazing as she was still recovering from an achilles injury.”
Team Mac were hoping to raise £1,000 for Poppy Scotland and have now passed the £1,500 mark, with donations still being received.
Janet said: “Friends, family and our B&B guests have been extremely generous in giving donations to such a worthy cause.
“The completion of the walk was particularly poignant for me as it was on Father’s Day and this was also a tribute to our dad and grandad.”
Natalie added “The tears were flowing at the end, for finishing, getting our medals and seeing the rest of our team including Les and Alex, our brilliant support crew.”
The Caledonian Challenge has been running for 15 years and teams have raised over £300,000 for Foundation Scotland this year alone.
