Twice on sunday and nine times next summer.
Well, everything states that the race does the circuit twice on Sunday, but it arrives from the south and leaves to the north. I think it must be twice up the hill, but really that's only 1.75 times round the circuit.
So far today I've spent over an hour trying to plan my visit, and I still can't with certainty answer the above question!
There's no confirmed start list (i.e. something I can take with me listing rider numbers for that embarassing Huw Porter-style moment when the break goes past and I don't recognise any of them). The list of timings looks like fiction. Almost all the maps are indicative rather than exact, although eventually I found this one that met my needs:

If there is any radio coverage - even local or at a feature level - it's not made it onto the listed schedules, whilst the only mention of any TV coverage is one thowaway sentence in Cycling Weekly.
And this is the highest profile one-day race to visit our shores for many years!
