One of Scotland’s most gruelling outdoor competitions pushed entrants to their limits on Saturday.
Nearly 300 hardy souls took part in the 17th annual Artemis Great Kindrochit Quadrathlon.
Stunning weather made for a truly memorable day but also posed its own challenges as they tested themselves against a 1.35km swim across Loch Tay and a 24km run over seven peaks.
If climbing 2,500 metres was not enough, they then had to undertake an 11km kayak crossing and a 54km bike ride in breathtaking Highland Perthshire.
This year’s winners, Drew Sharkey and Stuart Macleod, smashed the previous record by an incredible half-an-hour, completing the course in 7 hours and 37 minutes.
Close behind were the pair’s rivals, Sean McFarlane and Andy Gray. Sean won the 2016 event alongside Drew.
Amidst all the exertion, there was also romance as Euan Bell and Tessa Birley got engaged on the top of Munro number seven.
The fastest ladies team were Lydia Ashby and Alice Parsons, who finished in 12 hours 46 minutes, while quickest mixed team were local residents David and Jennifer Gane in 11 hours and four minutes.
David Fox-Pitt, founder of WildFox Events, said: “Quadrathletes this year saw Scotland at its very best with participants enjoying spectacular panoramic views of the Highlands as they tackled the course.
The event hopes to raise around £150,000, which will be split between the event’s charity partners, Mercy Corps and Mary’s Meals.
