That sounds like the bit on my commute. If you come up the canal lock 'steps' (you can ride up there) then if you look at sort of 1.00 you'll see a cobbled ramp. Take that, then turn left at the top. Left on Northgate Street (two way to cyclists, one way to vehicles) go through the lights, then take the second right, past Tesco express. Follow that road round the corner, take the left and go past the new bus station on your left. At the bottom of that road (George Street) turn right, go over Cow Lane Bridge and you can re-join the canal there. Head away from the bridge (without going under it) and you'll go towards Boughton, Vicars Cross and the A41. The canal path is paved to Waverton, after that it's not much different to riding across a field until you get to Hurleston junction, with just the odd paved bit along the way. There's a cracking pub at the side of the Shropshire Union near Beeston called The Shady Oak if you need a 'reason' for a pint or several!
Apologies if you already knew all this by the way.
