Winners of last year's Veteran Horse and Rider trophies, a Gold Award and the Exmoor National Park Accumulator Trophy - Carol Jones and Ptolemaeus from Tregaron, Wales.
The ride's organising committee has put on an extra class of 25 miles (40km) for the journalists. They will be escorted by riders from Endurance Great Britain's Elite Squad. These are horse-and-rider combinations from which the British endurance team will be chosen for the World Championships in Kentucky.
The Golden Horseshoe Ride, run this year from May 16 to 18, will again start and finish from the show field at Exford and will attract leading endurance riders from all over the country.
The route - which changes every year - will include Withypool Hill, Landacre Bridge Two Moors Way to Simonsbath then the Tarka Trail to Cheriton Ridge. Brendon Two Gates then north to Malmsmead for the halfway halt. It will then go along part of the southwest coast path to Pittcombe Head, into Hawk combe and up onto Ley Hill, Horner Woods, around the southern side of Dunkery, Luckwell Bridge, Stone Down and back through Exford to the venue.
The 40km route will leave the main course in Doone Country and covers Larkbarrow and Almsworthy Common before meeting back up with the main route at Hillhead Cross to finish though the village.
Also on the programme, on May 16, will be a 15-mile sponsored ride in aid of the Moorland Mousie Trust and the Dorset and Somerset Air Ambulance and the Golden Horseshoe Run, in aid of leukaemia research, when up to 100 runners will take on 14 miles of the 100-mile course. They will start 30 minutes before riders in the first class.
