so the phone is water resistant but my phone isn't so how will this work when riding and getting caught In storm. Also do I really want to carry the phone on every run? It doesn't make sense to me.
No, your phone is not water resistant. There are lots of water resistant and water proof cases available. I carry mine in a small belt pouch when I run. Also in that pouch is a ziplock bag to put the phone in in the event of foul weather.
