I don't think I made myself clear, so let me try a re-write:

There is one section of the park where you go as fast as 30mph b/c of it being so downhill, and I don't think my speedometer is broken, though I often don't go anywhere near that as my hands are on the brakes b/c of people traffic certain days of the week. After the downhill there's an uphill climb where you average 6mph on a windy day, and the rest is basically flat which will allow for 15mph or so. I'm one of the SLOWEST riders, as racers zoom past me...I guess they just ride more competitively.

The other thing is that the bike lane is NOT supposed to be shared by pedestrians b/c there is a pedestrian path in addition to the bike lane...unless I'm competely unfamiliar with the law? There are many cyclists who hit into people on the street who walk between cars into the bike lane, and maybe I'm wrong but I certainly don't see why it's the cyclists's fault. I remember once I was on the Manhattan Bridge standing in the bike lane instead of the pedestrian lane to take a photo, and I pretty much almost caused 10 accidents and vowed to be more careful in the future.

Is there anything I'm really missing here?
