Just under 4 miles with a fair amount of uphill.
Starting from the Memorial Hall car park go to the roundabout and turn right up Marsworth Road into the village.
After about 200 yards take the smaller gate on your right into the permissive footpath surrounding the allotments. Do not enter the allotment site.
Follow this path round till you come to the farm track. Turn left and follow the track straight till you reach the B488 by the Silver Birch. Beware that this path can be muddy in parts in the winter.
Cross the B488 taking great care. This is the safest place to cross the road. Cross the field on the permissive footpath. Go through the hole in the hedge and turn left onto Footpath 7.
Continue on the footpath over a stile, across the field entrance and round to your right parallel with Stocks Road to climb the hill.
When you go through the gate at the top of the footpath keep walking up the hill past the Anglian Water inspection field to Pitstone Hill car park.
Cross the road at this point and continue along the wide track beside the field until you come to the corner with a crossroads signpost.
Go right along the side of the field till you come to a post in the path. Keep to the left hand path up the hill unless it is very muddy when it is possible to divert up the grass.
Keep going up till you come to a gate. Go through the gate and take the diagonal path up continuing in the same direction.
You will come out onto a potholed gravel track. Bear right and continue till you come to the Kennels. Follow the made up track along the boundary. This is the beginning of the wide track which is easy walking to the monument still some distance away.
It is also possible to start this walk by going through Ivinghoe across the T junction of the B488 and 489 and through the gate up middle path about 200 yards further along. Rejoin the walk at point 5
