I'm still pretty new to all this and so far.. I've just been riding on the Alameda Creek Trail/Coyote Hills and just around town. Those are perfect.. pretty flat with small hills occasionally. Just looking for something new.
I just bought a bike rack so I can travel places with my bike.. but I'd prefer to keep it closer. I'm in Union City and I ride a fixed gear bike. One thing though, is I try to stay out of graveled roads.
