This is possibly the best and most polished version of Ur on this site. The sounds and animation logic for hopping or sliding the pieces are a nice touch.
If you're interested in quality of life improvements, the camera switching sides between player turns is slightly distracting, especially when a zero is rolled. I know people often like to see a chessboard from their side, but I doubt a race game really needs it.
Rolling the dice with the spacebar would also be nice, since I'm playing on desktop.
Other than that, it controls very intuitively. I've played versions that required me to select the piece and then the location, as if this were backgammon. Your version makes much more sense, since the dice can't be split.
I have to ask, is the whistling in the background based on the song from the Bad Lip Reading video on The Emperor Strikes Back?
