The first signing-on session for the 1,700 entrants for Sunday's Manx Telecom End to End Mountain Bike Challenge takes place this evening.
It's at the Grill in Nobles Park between 5pm and 8pm.
The 75 kilometre route between the Point of Ayre and Cregneash is a mixture of roads, plantations and moorland paths.
There are some changes this year - Ballaugh plantation is not being used due to Ash dieback and a new trail at Arrasey is being used for the first time.
Organising Committee Chairman Steve Honeybone says Slieau Whallian climb has also been dropped:-
