Thinking about it there is tons to ride but I dont know anyone with one other than for doing that Gateshead race series.
Northumberland costal path – Cresswell all the way up to Alnmouth – along to Howick and Craster even. Bridleways around Acklington, Warkworth would be good, again Ingram and even most of the cheviots would be good.
If I had the time, cash and space I think id have one for rides across to Morwick Ice cream palour in the summer.
