Cyclists are aiming to raise up to £100,000 for a cancer charity as part of a three-day challenge to travel from Edinburgh to Dublin.
The 220-mile cycle from capital to capital will raise money for Marie Curie Cancer Care.
Organisers are looking for 60 people to take part in the event which starts on July 12.
Robbie McIntosh, the charity's events manager for Scotland, said: "The Edinburgh to Dublin cycle challenge is set to be an unforgettable experience for all involved.
"The 220-mile route takes in some of Scotland and Ireland's most beautiful roads and countryside while raising funds to enable Marie Curie to continue its invaluable work throughout the year."
Those wanting to take part will have to pay a registration fee of £150 and pledge to raise a minimum of £1,250 in sponsorship.
Costs cover accommodation, meals, the ferry crossing and return flight to Edinburgh, plus a support team including a bike mechanic who will be on hand throughout the trip.
Marie Curie Cancer Care employs more than 2,700 nurses, doctors and other healthcare professionals, providing care to more than 31,000 terminally ill patients.
