Very interesting - I suspect you need hearing protection for an event like that. It looks like a fairly slick surface for that type of racing. Is this track used for any other type of racing?
great captures for that hard venue! the lighting on indoor sports ia hard enough now they are on even faster bikes! That racing looks crazy, I can't imagine how those bikes handle in a small are or on that surface.
I’ve photographed on concrete perhaps a 1/2 dozen times and this a little tougher in that you are creating images by shooting through a chain link fence . Average iso was 3200 with no flash. They use carpet remnants and works fairly well. There’s a variety of bike sizes starting at 150ccs and going up to 450cc with some 2 strokes thrown in the mix.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
