There are three main ways of viewing the Tour: watching
the race, the start, or the finish. Each is its own unique
experience
and is worth it if you have the time. Obviously, the best way to see
your favorite riders racing is on a climb, and the excitement is highest
in the Alps and Pyrenees. You can get local publications that estimate
when the peloton will arrive at all points throughout a stage, use
these to pick a viewing spot (VeloNews also produces a guide). Pack
a lunch, arrive as early as possible and ride a bicycle if you can.
Naturally, parking is limited in the mountains and after the stage
there will be one huge traffic jam! Cycling will also allow you to
be more mobile in getting to that incredible spot high up on the climb
(not to mention you are actually riding on the course). Relax and
people watch.
