Saturday at 10 sounds good. I've done the route from the station, Sports Park is the wrong side of town for this route.
I did a recon mission today, and have revised the proposed route to this:

Possible stops are:
Quick detour into Heydon, it's very nice and I think it had a cafe and a pub.
Sheringham, or can not bother going into Sheringham itself and stop at Pretty Corner tearooms.
Cawston, has a pub, don't know what it's like.
And at the end, the Coach and Horses pub near the station is very good and serves food.
On the offchance ~55 miles on fixed hasn't finished me, I can arrange an extra 10, 20 or 30 mile loop, all of which have pubs as potential stops.
