What you’re in for

Held in Hulne Park, the Northumberland Estate's walled park next to Alnwick Castle. The 10K is one lap and the half marathon is two, on park paths and farm tracks with some undulation; the 5K is flatter. There is no traffic on the course. The races are chip timed and part of Run Northumberland's Castles Challenge series. Race HQ is in the field at Abbey Lodge. Dogs are not allowed anywhere on the estate, including with spectators. The minimum age is 17 for the half and 15 for the 10K, and there is also a junior 2K.
