Newmarket's race course issue

[doris_day]

I have a whole load of data which is separated into 'July course' and 'Rowley Mile' for Newmarket.
Can anyone tell me which course they were using yesterday and today ?

Thanks

PS An interesting sideline to this is that over the years I've found my algos quite often perform poorly at some courses (to be expected) and more often than not the same bad courses turn up time after time (not expected). Even though the alogos are based on totally different factors. I find that interesting.

It appears that the Tote show which course this is.
