Circular routes - back to the beginning?

[ampthill]

Right, I have made a number of circular routes in CN8 for an Alpine tour later this year. NB. good source of ideas is the book 'Motorcycle journeys through the Alps".

The idea is that I will follow a circular route each day. Having made these routes I am aware that I might not start them at the point where I have currently started them from, but may start at a later point on the route. For example I may have a circular route going Chamonix - Martigny - Aosta - Morgex - Chamonix. However if I was to start at Martigny instead of Chamonix am I right in presuming that the GPS would take me back to Chamonix and then I would have to restart the route to get back to Martigny. Am I right with this? Some expertise much appreciated

Am I right with this?

Yes (with a Nav II/2610 - I presume the same for other makes/models) - don't forget to set the GPS to "Do not recalculate when off-route".

Haven't tried it myself, but if you store all your waypoints on the GPSR and do a route from Current Location to Current Location via the waypoints, would that not do the job?

Doubt it - usually it says "you've already arrived" without going anywhere - normally for a circular route you have to end up at a waypoint which is a short way "behind" you.

Fair enough

Interesting point - so if I create a circular route of lets say, 200miles, and I have the starting point and the end point in the same location the GPS will not send me by any via points as it thinks I am already where I want to be? I suppose there has to be some logic in that! So howabout I then set off anyway in the direction of the first via point, will the GPS then prompt me to go through all the other via points I may have set up?

So many questions, but I'd rather address these issues now rather than when 1000 miles from home

Right I've just got back in from answering my own question... I uploaded a circular route to my Quest using my current location as both the start and end point. I then went outside and asked it to take me on my route. sure enough it wanted me to go out the driveway, pass the via points and then return back to the drive.

That's exxakkerly what I did on the fords ride this weekend....what a twat

As mentioned before, you can set the GPS to notrecalculate your route then it'll keep punting you around the circuit rather than realising that the shortest way to theend point is to turn around.....or better still (to get you back on the circuit if you do deviate but not just asking you to turn around) plan the route in two halves, with the furthest point away as the end point for the first half and the start point for the second (with the original destination/start point as the last point in the second route)

I think you'll see what I mean

The answer depends on which GPS-model you have. For most models the answer is yes, you need to restart when you pass through point zero.
