Welcome. I guess you have to decide how commited to riding in the rain you are. There is plenty of great rain gear you can buy and lights for night riding. If not get yourself a good trainer and go to spinning classes. I ride in the rain all winter and I like it better than a trainer but its not for everyone. Also so many people do STP you shouldn't have too much trouble finding people to train with,just make sure you register early I have friends that didn't get in this year. Good luck
I like bikes, sometimes more than my husband
