The Tarrant Valley 10 comprises a multi-terrain 10km race and a separate 1-mile children's race, hosted by the village of Tarrant Monkton, set entirely within the Cranborne Chase Area of Outstanding Natural Beauty. Both races start and finish in front of The Langton Arms pub right in the heart of the village.
The 10km race begins on tarmac roads but, after the first kilometer and a challenging ascent into Hogstock Coppice, the course continues on well-surfaced bridleways and farm tracks. Relatively flat through Sing Close, Long Row, and Calcott's Coppices, half-way is reached at Six Cross Ways in Chetterwood. Past Strawberry Coppice and a gentle climb to Launceston Wood, the course then opens out to deliver a quite spectacular view over the North Dorset countryside. An exciting 800m descent on Common Drove leads to the road once again and a 600m sprint through the village to the finish. Approximately half of the race is in shade.
