The course runs from the Northampton Holiday Inn in a 5.17 mile loop along the River Nene and around several flood storage reservoirs. It's 100% off road. 45% tarmac, 55% grassy trails. For those who want to complete a marathon distance we'll have a 0.35 mile out and back near the base camp to make up the full 26.2 mile distance.
