I think the big issue with speedway ever returning to Odsal is the new stand at the top of the picture. The supporting legs at the front are very close to the outer perimeter of the track and could be a danger to a falling rider. It also wouldn't be able to host any high ranking events as, although the bends are wide, the width of the straights is below the minimum requirement for any FIM competition.

Doesn't bother the Stock Car people. I'd try some open meetings, it would then be a neutral track, no home track advantage, might be better supported than expecting fans to turn up weekly, that would be easier to accomodate date wise, fitting in with the Rugby & Stock Cars, stick to May to September. I'm sure fans will have other ideas that may be feasible.

It looks like you can watch highlights for free on dmax on the discovery + app

Did you phone up to get it, my BT account says £20 for 24 month contract 

I wouldn't argue with that. Bartosz Zmarzlik is a great rider, but crucially, does little to help Speedway outside of Poland. Publicity, Marketing etc.

Looks perfect for speedway but the place would look empty even with crowds between 1-2000.
