More than 2,500 people are set to descend on Huddersfield for a major sporting festival.
And the action will be based in the countryside and woodland on the sprawling Storthes Hall site.
The competitors are taking part in a huge orienteering festival, which runs for four days over the Easter break across venues in Yorkshire.
East Pennine Orienteering Club have managed to secure the final leg of the Jan Kjellström Festival for Huddersfield and hope it will be a massive success.

Race organiser Amanda Crawshaw said: “It should be a great finale to the four-day festival, with thousands taking part.”
Orienteering is an outdoor adventure sport which involves walking or running whilst navigating around a course using a detailed map and sometimes a compass.
The aim is to navigate in sequence between a set of control points and decide the best route to complete the course in the quickest time.
Competitors can run, walk or jog the course and progress at their own pace.
Orienteering can take place anywhere from remote forest and countryside to urban parks and school playgrounds and is described by afficionados as a great sport for runners, joggers and walkers who want to improve their navigation skills or for anyone who loves the outdoors.

Jan Kjellström was a Swedish orienteer who played an important role in the development of the sport in Great Britain. Tragically, Kjellström died in a road accident early in the year of 1967. That year saw the first Jan Kjellström International Orienteering Festival or “JK”, held in his memory. The annual JK festival moved to Easter in 1969.
Monday will see the relay stage of the festival at Storthes Hal, with races getting under way at 10am.
Amanda said: “It is a true international event with contestants from as far afield as New Zealand, Australia and Scandinavia.
“We have got some elite athletes in there and some of them could well be competing in Olympics events in the future.
“But equally we have people aged up to 90 and children as young as seven set to take part.
“They wil be in teams of three who have to navigate their way round a course through the complex. For the elite athletes, it is very much who is quickest but for others it is more of a fun event.”
The races get under way at 10am on Monday.
