The Lincolnshire TT is a great loop starting in Melton and covers some of the best roads East of Leicester.
This is only a very short route but a nice one. Meet at the Red Cow pub, which has a nice big car park, a beer garden and a conservatory, and they do food. Then it's a ten minute whistle down to the track for a day's race along some very nice roads with lots of room for overtaking on the A47 if needs be.
Lots of open corners with good visibility on this stretch. Be aware of some Police presence, even sometimes from the air.
This route is my favourite, plenty of twisty bits and enough straight parts for overtaking the best bit though (for me personally) is the straight run across Blithfield reservoir which leads into a great left-hand uphill bend at the other side just be wary of oncoming traffic coming in the opposite direction once your going up and over the hill
Not that twisty but a couple of nice corners. Good selection of flowing medium/high speed corners, watch the last decreasing radius corner by the zoo, it can catch you out. Be aware that sometimes Police lurking in the layby on the way into Twycross village.
