Event Details


This is an extreme endurance event in variable conditions and water temperatures, requiring the highest level of mental determination. Although full safety cover is provided, the swimmer is expected to source a suitable escort boat and provide crew for it. This aspect of the swim is at least 50 % responsible for success. It is an overnight swim with a staggered start to try to achieve an 8am finish for everyone. Past times have been between 9 and 26 hours!

There are only around 60 people who have completed this swim, the first one being Commander Gerry Forsburg in 1959. As a result of our amazingly successful anniversary relay in 2019 we are offering a new relay event to be held in conjunction with our end to end event. For more information on this please contact Janet as below.

Price £350.

You need to arrange your own support boat and crew, this is a critical requirement and boats on the loch can be booked up to a year in advance. There are not many hire companys on the loch so you need to do your research and get it booked early (i.e. don’t leave booking boats and accomodation until 2024 you need to be getting it sorted now to ensure availability)
