Cool project. Do you have a specific question, or are you just looking for input?
If you are aware of 20mm optics, I’m guessing you know that they come in clear, frosted, small spot, med, wide flood, and elliptical. I use a DIY sopt+elliptical 20mm optic combo for bike commuting and recommend it, I might think that it would be similar for your application.
One piece of info that I think is missing is how much light you want/need. How many lumens, or how much throw do you want? What is “Low” and “High” that you mention? This will be critical in determining if you can run all night on one set of batteries.
What kind of controller or driver do you plan to use?
Another question I have is - do you really need light at all times? Your human night vision is pretty good if you are able to let it adapt. But if you are going to be hit with artificial light from other racers or from the racecourse, then obviously this won’t work
