BIKE TRAILS OF ANCHORAGE!! I love this website. Maps, descriptions, and photos of the various PAVED bike trails in Anchorage. One year, I even printed out the maps and kept them in my bike bag.
BICENTENNIAL PARK TRAILS!! If you like mountain biking and offroad single-track, here is a link with maps of Bicentennial Park and Campbell Tract trails. Bears do roam those woods, so be aware (and there is a bear aware class listed below on 5/2)
