I do get annoyed when councils and various other groups in London talk about the canal towpath being a traffic free zone. It is not! Part of the traffic that should use the roads (cyclists) are now using the towpath. Cyclist ARE Traffic! Not only are they traffic many of them can be inconsiderate bastards into the bargin. If they drove their car the way they ride their bikes they would almost certainly lose their licence ‘Driving without due care and attention’.
No pedestrian should be placed in danger on a footpath. If cyclists can not show due respect for the vulnerable then they should get back on the road.
Yes I know the road is not always a suitable place for cyclists, but that is no reason to put pedestrians in danger. Riding to work at speed along a pedestrian populated towpath is at best a folly and at worst downright dangerous.
If a person needs a daily fix of adrenalin then he should get up earlier and go to the gym. A racing cycle is not the right equipment to use on a crowded towpath.
