In need of £50,000? Snap a selfie with the Loch Ness Monster and the money's all yours.

Runners in the Baxters Loch Ness Marathon, an annual race held in the Scottish Highlands, will have the chance to win £50,000 if they can produce photographic evidence of the legendary marine reptile.

Runners need only snap a selfie with the monster in view and submit it to the organizers, who will work with the Royal Zoological Society of Scotland to determine its authenticity. More than 9,000 participants are expected to run in the marathon on Sept. 27, and race director Malcolm Sutherland felt this would be a great chance for runners to keep an eye out.

"We realised there was a potential for our runners to help prove once and for all whether there really is a pre-historic monster living in the loch," he said in a press release. "With so many selfies being taken on race day, surely if she is out there someone will be able to get one with her in the background."

Loch Ness Monster sightings dried up between 2012 and 2014, leading to speculation that the ancient reptile had disappeared for good — that is, if she was ever real in the first place. But Nessy sightings picked up again last spring after an Apple Maps satellite image appeared to show a large creature swimming in Loch Ness.

But whatever your opinion regarding the Loch Ness Monster, this brilliant bit of marketing for the Loch Ness Marathon is bound to increase interest in the ancient legend. But for the chance to prove the existence of a centuries old legend seems worth a whole lot more than just £50,000.
