Received a reply from Alan this morning. He is not a member of the forum so as a guest can't post at the moment (I'll work on that!)
Hello Janet
Nice to hear from you again and it looks like the return of speedway in Leicester is getting nearer.
I have read the comments on Speedway Forum and as you say I am not a member. perhaps I should be!
However, the track was built on land that formed part of Lodge Farm in the parish of Belgrave. The old farmhouse was converted to a clubhouse and the outbuildings were adopted as a workshop for the mechanics. This may help the person to locate the site who was looking on the Ordnance Survey map.
Of course the features of Melton Road has changed somewhat since 1929 when the Super was built. As you can see from the details above, there were no properties, only fields. But to give you a fix, on the way out of Leicester on the right hand side just before the X roads where Thorn Lighting stands there is (or was) a building that was occupied by Iceland (Frozen foods) and the track was situated in the fields behind this building.
Hope this answers the question.
Regards, Alan
