The SCS Relay takes place at Ballannette Farm in Lonan today (Boxing Day).
The event was held for the first time a year ago, as a replacement for the Millennium Way Relay which was stopped on health and safety grounds.
It too is a four leg handicap relay, held over a three and a half mile trail.
Legs one and four are two laps of the course so covering seven miles each and are for the fitter or faster members of teams.
Legs two and three are then run over one lap.
Teams therefore complete six laps of the route in total.
The handicap will run off 10km times which are used by the handicappers to provide estimated times for the two lap and one lap legs.
The slower teams will set off first followed by the faster teams later.
Elsewhere, there are several Rugby friendlies including the Paul Clelland match at Ballafletcher between Vagabonds and the Young Farmers.
Other clubs orgainsing matches include Douglas, Southern Nomads and Castletown.
