The race is an officially measured and certified by Scottish Athletics road marathon based in the Outer Hebrides on the West coast of Scotland. The start is at Lochboisdale Marina on the Island of Gasay and the finish is at the Dark Island Hotel, Isle of Benbecula.

The race can be run as a Solo, Pair or teams of 3 of 4. There are 4 legs between 5.8 miles and 7 miles in length with 3 changeover checkpoints.

There is also the Community Teams which are made of names who have entered under the individual category but are not running the full distance, all the names in this category are drawn at random to make up a team to cover the 4 leg distance. You do not have to be a local to enter the team draw, the draw takes place 1 week before race day.  There is a separate prize Category for the Community Teams.

There are Solo prizes for 1^st,2^nd and 3^rd Male & Female along with various Vet categories. There is no “traditional” team prize for first 3 from the same club for example.

There are Male, Female and Mixed categories for Pairs, and teams of 3 or 4, 1^st place only.

The Community team has no gender related categories as the draw is totally random, however, there are 1^st, 2^nd and 3^rd placed team prizes.
