My friends and I plan to watch the Tour De France at the roadside next year. We're targeting the weekend of the 6/7 July and would like to be near the top of the climbs near the end for both stages.

I know that a lot of people actually camp on the roadside overnight to get a good spot. Is this the only way? Have any of you done this before? Would it be worthwhile taking our bikes?

Any advice you can offer would be much appreciated.
