I never do, never crosses my mind, and the only pedestrian/cycle path I use is one coming up a local hill if the lights are red, its literally about 20ft and is designed for such, this is a personal thing but traffic doesn't bother me, not even on the A1 (though that was a mistake, I fell very ill whilst out on the bike one day and got totally disorientated)
The M.T.Bikers. I am referring to were coming down the opposite part of the above mentioned stretch of road (not the A1), where the path is no more than a push chair width.
