Racing in the rain is the same as racing dry, except you get wet! Logical , eh?

Your booties will keep all the moisture out for a total distance of about 30m. After that they keep you feet warm and wet, so your skin goes white and swells up massive inside your shoes. You get used to the squelching in your shoes after a while/your feet go to sleep.

You have no brakes. Neither does anyone else. Carry on.

You will be able to identifiy various parts of the course by taste.

Your glasses will fog up plenty and get covered in **** all the time. You will run out of rinsing water at about half distance. After that you'll be forced to try to wipe them clean. This will only scratch the lenses and smear grease all over them, making them useless. As soon as you take them off in order to see the rider ahead will flick a tiny bit of road grit into you eye.

A bunch sprint is not a desirable thing.

When you get back to your car you will discover that one of your windows was slightly ajar and all your warm clothes and the seats are now cold and wet.

Oh yeah, and you will need to clean your bike when you get home. Level 3 water restrictions are in place: don;t waste water
