A spectators guide to the Tour de France

You would like to go to France and see something of the Tour de France. But how? How can you get the most out of your visit? What can you experience? How different is watching live to watching on TV? Is it worth the cost? All questions I attempt to answer from my 9 years following the Tour de France around France. And of course, there is France itself! France is stunning.
Everyone should visit the Tour at least once. This book will provide information on logistics, planning, opportunities, and what to expect, where, and when.
I provide tips for every type of opportunity that is possible on the different stage profiles so you can decide what suits your hopes for your visit best. I give practical information and example days on each variation.
It’s also a good read! I have experienced so much that every one of the 149 days I have spent at the tour has something worth talking about, but have had to limit the example days to just 31.
If you are not sure what to do for your holiday, go to the Tour de France! You will not regret it.
