This will depend on each person riding their bike, when we used to up into the lake district in the seventies we had over a hundred bikes in tow, granted all were experienced riders, but you just leave a good amount of distance from the bike in front of you. It is like doing a funeral march,

If everybody thinks its too much hassle, we can always stop on site or go our own ways.. Whichever suits at the time..
