Dundee man Grant Laing died while cycling on the remote Applecross peninsula in Wester Ross at the weekend.
Mr Laing, who was 42, grew up in Broughty Ferry and Barnhill. He had been living in Perth and working in Uddingston for company Balfour Beatty.
A keen rider of mountain bikes, Mr Laing had been away for the weekend with partner Annette Spence and two other friends when he suffered a heart attack on Saturday while out riding.
The members of the party made attempts to contact the emergency services, but were hindered due to patchy mobile phone reception. They also administered CPR.
After making their location known, HM Coastguard sent a rescue helicopter to airlift Mr Laing to Dr Mackinnon Memorial Hospital at Broadford on Skye, but he could not be revived.
Educated at Barnhill Primary and Monifieth High, Mr Laing went on to study civil engineering at Abertay University in Dundee.
He went straight into employment in civil engineering and had been working most recently for Balfour Beatty as a bid director for the new Forth Crossing.
Mr Laing had been with the company for almost 10 years, working as a bid manager, but he was asked to take on the year-long role as bid director for the landmark crossing tender.
Described by his family as a man who lived life to the full, as a youngster Mr Laing was a keen swimmer, water polo and rugby player.
His major passions were extreme mountain biking, hill climbing, music and travelling.
He had completed a number of treks, including the Munros Ben Vorlich and Schiehallion.
Mr Laing also journeyed to the Ladakh district of India last year with a group of friends to scale Stok Kangri, one of India’s highest trekking peaks at 20,138 feet.
In addition, he participated in mountain biking events such as the The Corrieyairack Challenge near Kincraig in July and also the Strathpuffer race in Strathpeffer in January, which lasts for 24 hours.
Partner Annette said, “Everything Grant did was to a massive extreme and he put as much of himself into his passions as he did to his work, his family and his relationship.”
Mr Laing is also survived by mother Jean, father Ian, sister Allison Hay, brother-in-law Peter and two nephews.
