Next weekend, Holyrood Park will play host to the much-anticipated Simplyhealth Great Edinburgh International XCountry – here is your run-through of the events and how they work.
Thousands of spectators are expected in Edinburgh to witness the mud, the grit and determination of cross country athletics, with the event televised live on BBC One.
Team GB will once again take on Europe and the USA in a thrilling team competition on a tough cross country course in one of Edinburgh's most iconic locations.
The overall winners will be determined by the best aggregate finishing positions of the six best placed athletes in the senior category, as well as the four best placed athletes in the junior races.
This all takes place after the annual mass participation Simplyhealth Great Edinburgh Winter Run in the morning, where 3,000 runners will blast away the New Year cobwebs on a 5km course around Arthur's Seat.
