City Bicycle Works doesn't have anything in your size. I asked for suggestions of any other shops "in the area" and they suggested Bicycles Plus in Folsom, which we already determined is too far for you travel, unless you want to spend time on the light rail. I will message you with info on Bicycles Plus, and also other stuff to do in Sac. You can still use the same American River Parkway trail for running. It really is a beautiful location and easily accessed from downtown/Old Sacramento.
