Depends…There is a much faster, nicer route, mainly off-roads…but dont take an expensive bike – its Manor Dahling 😉
When you leave work (AMP?) pick up the bridleway opposite on the left as you head back up the hill towards the roundabouts under the parkway (opposite the Sanderson(?) office). This will take you off-road nearly to Asda on the Parkway. Keep alongside the Parkway all the way – lots of in/out bits with some woodsy bits, some steps etc. Mind the burnt out cars, dumped fridges and kids skiving school for a tab in the woods…It chucks you out on Manor Way, where you can do a left turn uphill for 10m or so, right down Maltravers Road and you are at the incinerator – I would then do a left along Bernard Street and Talbot Street (you would now be behind the station with nice view, and some cheekyness in the Plague Park if wanted), and onto the inner ring road at Sheaf Square
