Three members of the Galloway Mountain Rescue Team are taking on a 12-day cycle challenge to raise money for their service.
The mammoth challenge will see them reach the four compass point extremities of the Scottish mainland.
They are hoping to raise a tenth (£2,500) of their annual running costs (£25,000).
The challenge starts on Saturday (6th July) from their rescue base in Newton Stewart.
The cyclists then head for the most southerly, westerly, northerly and easterly points before returning to Galloway.
"David Tyson, Ken Mackenzie and myself, are keen cyclists and have undertaken a number of challenges in the past. This is however our most significant to date.
"Many fund raisers cycle from Lands End to John O' Groats, a distance of around 840 miles, however the route we will take is an additional 160 miles. A total of 1100 miles.
"The majority of the money raised will go to the team funds to pay for equipment, training, vehicle running costs and building maintenance.
"A proportion will also be donated to CLIC Sargent, the Children's Cancer Support Charity."
