Wear a hat. This is particularly crucial if you have glasses, but regardless I think just keeping the rain off your eyes can do wonders to make it less annoying.
Be visible. Even if technically during "daylight", the rain makes things dark and gloomy. Wear bright colors and make sure cars can see you!

Consider trail shoes. Particularly in the fall, I like to wear trail shoes so I have a bit of extra traction over the wet leaves and avoid slipping.
Protect your stuff. Put your phone in a bag if you think it'll get soaked; have a cover for your stroller. I debated buying a weather shield for the stroller, but I can't even imagine not having it now - I can take N with me through rain, wind, or cold!
Enjoy it! If I'm looking forward to a run, it doesn't matter too much; but if I'm on the fence the rain definitely isn't encouraging. But it can't be avoided, so you might as well enjoy stomping in some puddles!
