Hahaha, yeah, ok roughly... 32mph is km im 70 seconds, which means that 500 yarder is going to take 35 seconds.
It's take patience to not go from too far out, and the headwind will only make it worse.
If you get a chance before the next race, roll backwards on the course for 1k on your computer, and make a visual refference if you can, same for 500m and 250. It may help you later.
