Absolutely agree with above poster...especially when applied 1 hour before your run.  The stuff has been great!

i live in az; i agree neutrogena is the best.  but it is pricey.  i use it for lunch runs.  i also keep some cheaper stuff in the shower, especially during the summer, and use it instead of moisturizer right after showering.  i also often wear long sleeves and always a hat.  best of luck in san diego!
