I've deviated from the original plan as it meant it was not a round trip (for picking up cars, etc), accommodation would be in the Youth Hostel on Islay to keep costs down/it simple/avoid camping, and the middle day ride to Jura is optional so those who are into more "extreme" form of cycling (@
ShooglyDougie !!) could always plan a different excursion. I've tried not to rely on the last ferry of the day where possible, and we will probably be limited to how many we could book in one party (though could always book separately or into a hotel if that's your thing).
I'll reiterate this is all just musing on my part and subject to change/abandonment at this stage, I would need to know that you would be responsible for all your own costs (and yourself), there will be little/nothing in the way of bike shops so running repairs might be necessary and agreement that if you are too hungover to cycle on Day 3 Top Gear rules apply - you get left!
Thoughts???
