Since my husbands cardiac arrest, we've been walking the track, getting healthier and stronger. There's some spots where the track has missing pieces of the rubber layer. I really appreciate that rubber layer as my knees are needing replaced. This layer adds allot of cushion, nice shock absorbing quality. There's plenty of this layer that you easily go around the missing. We go in the morning and there's maybe 1 other person. The earlier you go, the less people you encounter. Nice place
