A selection of practical routes from Badger Farm within Winchester.
Check out the routes on RideWithGPS.
These routes are primarily the most efficient routes to use; generally they follow quieter roads and avoid some difficult junctions. Of necessity the routes will include sections of main road.
They are intended for reasonably confident cyclists.
These routes will typically take 10-15 minutes door to door; rather quicker than by car. The uphill return to Badger Farm will take longer unless you have an e-bike!
Here’s a route I use from Fulflood to the High St. A bit wiggly but avoids main roads
