Last night and the night before I was pushing my 3 speed over the Longstone Aqueduct heading west. I let two bikes come past with the wind behind them. I operate on a principal that if the oncoming bike is over half way it has right of way and I let it pass. I push bike against railing and stand on the wall. If I am over half way and a bike comes on going in the other direction I feel I therefore have right of way.
Sometimes there is a 50/50 too close to call e.g. if you both come on at the same time. Then it is usually who cracks first or indeed both parties stopping.
I always give way to people on foot.
Other etiquettes are available. E..g if on railing side (ie heading east) yu should always give way. Mixed etiquettes can lead to some minor unpleasantness.
The sign says dismount, this is largely ignored.
Does anyone else have a view [admittedly I have bored myself by this point in the post but in the spirit of our little community, go on, let me know]
