All routes follow the wide gravel paths around the Stanwick Lakes nature reserve.
Runners have to cross the entrance drive to the site on all distances, and Half Marathon runners also cross an entrance road to Ringstead Marina — all road crossings are marshalled.
Direction markers are placed around all courses to keep you running in the right direction. Due to all courses using the same paths, we have not been able to add distance markers.
The Half Marathon follows the 5K course but then splits off to follow the old Nene Valley Railway line towards Thrapston. Once runners reach the turnaround point (under the bridge at Woodford Mill) they run back down the railway line to re-join the 5K course. This is done twice to achieve the correct distance.
There are 3 road/track crossings per lap on this course, all marshalled for your safety.
