I asked for a map at BW, it only has the distance around the lake, about .8 mile. BC had a map that had several more routes, one was on the sidewalks around the whole BW, BC, YC, S/D complex (sorry, forgot the distance) and one going up along the creek by the Swan, over the bridge and back on BW side. That is the route I do, a lap around the lake, then up to the bridge and back and around the lake again. I guess it to be around 3 miles.
Happy running!
