Marshals are needed for this weekend's E2E mountain biking challenge.
Anyone who can spare a few hours of time on Sunday is asked to volunteer.
Organisers say it is not an 'onerous task'.
In a plea on Facebook they write: "Please don't forget that by supporting the E2E team you are supporting sustainable trail building on the Island.
"The trails don't build themselves and the current E2E team don't just look after the E2E route, but countless miles of other xc and enduro trails in partnership with DEFA and a band of great builders."
Anyone who can help is asked to text 07624 452428.
