Friends of a Chorley man who died suddenly of a heart condition are completing the challenge he was never able to do.
Daniel Page, from Euxton, died aged 31 in January, leaving behind wife Anne and eight-week-old son, Thomas.
He had always wanted to take part in the National Three Peaks Challenge across England, Scotland and Wales, but never got the chance.
Now, his devoted friends are doing the trek in his memory, and are raising money for the British Heart Foundation (BHF) at the same time.
Ian Hayhurst, who was Daniel’s best man on his wedding day, said: “Dan was a very active and outgoing guy who had numerous outdoor hobbies like cycling, walking and camping.
“The Three Peaks challenge was something Dan wanted to do, so it is fitting that we can raise money for the British Heart Foundation in this way, and in his name.”
Dan, a paramedic from Countess Way, died of a heart condition called coronary artery atheroma.
He had been cycling to Rivington with a friend when he collapsed and was rushed to hospital, but never woke up.
Now, 13 of his friends are preparing to complete the Three Peaks Challenge to raise funds to help BHF research.
The trek will cover 26 miles of gruelling mountain climbing, as well as over 475 miles of travelling from mountain to mountain - all within 24 hours.
The peaks are Ben Nevis in Scotland (4409ft); Scafell Pike in the Lake District (3209ft); and Snowdon in Wales (3560ft).
Walker Emma Kerrigan said: “We practiced on Helvellyn, Old Man Coniston and Parlick.
“We are doing it in memory of our friend, and we want to raise as much money as possible for the British Heart Foundation.
“Money raised for the charity enables them to research causes and cures for heart conditions.”
The team are doing the challenge on August 27.
Preston Community Transport is providing the fundraisers with a minbus to tranport them from mountain to mountain.
