RR 12 Sustainability Centre to Warnford Road (Exton) You can either use the road itself rather than the SDW path next to the road (with a hedge between it and the road) Note "Only the clearly waymarked SDW route to the south of Old Winchester Hill is permitted ." Note "At the disused railway bridge, any route over or under the bridge is permitted. After the railway bridge either the river bed or the path to the right of it can be used." (It's quicker and easier to run along the stream bed - the path is criss-crossed with roots and low trees.) Note Follow the sign saying 'temporary footpath', don't take the alternative southern SDW route for horses and cyclists via the disused railway line. Note
