Swimming, cycling and running event starts

A 2km (1.2 mile) swim in Port Grat Bay is among the events

Competitors are swimming, cycling and running around the west coast of Guernsey for the first Granite Weekender.

The multi-sport festival for experts and novices on Saturday and Sunday will include entrants from Jersey, the UK and the Netherlands.

Among the challenges are a 2km (1.2 mile) swim in Port Grat Bay, an 80km (50 mile) cycle along the west coast and an 18km (11 mile) run.

Amy Critchlow, Island Games triathlon bronze medallist and one of the organisers, said many competitors had been inspired by the biennial Island Games.

Roads warning

She said the events in "such amazing scenery" were going to mean an "amazing weekend of adventure".

Although most of the weekend’s events will be taking place on open roads, road access to the Port Grat East Car Park, Les Dicqs, Let Petit Clos, Rouse and Rousse Car Park (including Rousse Kiosk) will be closed from 06:00 to 15:00 BST on Sunday, said organisers.

During this time, although pedestrian access will be available, no vehicular access (including bicycles) will be permitted while the events are taking place, including access or egress to properties business or parking areas.

The only exception will be for emergency vehicles.

Fellow organiser Sam Gosling, a former triathlete, said: "We really appreciate this temporary road closure will cause disruption but are keen to ensure the safety of both competitors and members of the public remains of paramount importance.

"We are also aware there will probably be more cyclists and runners out along the west coast and around the quarry than there usually are on a Sunday morning."
