I'd say less than 40 minutes on a bike! But I guess you'll need to factor in some extra 'event' traffic near to the circuit.
That’s a good price actually. One just needs to get a cheap flight and then one only needs one’s summer riding gear, not the 3 seasons stuff that would have to be taken if one were to ride all the way there.
ok so for anyone flying ignore this advice https://www.docgb.org/world-ducati-week the closest airport by far is rimini and theres a very cheap direct flight from heathrow
so accomodation pre-booked just in case anyone is looking - about 700 eur for 4 nights https://www.hoteliberty.com/ i have also pre booked an air b n b in cattolica which is about 6km ride from the circuit - about 600 eur 4 nights
Iv booked a weeks stay half board in hotel vanni in misano, iv stayed several times and find them 1st class and family run. Also franki chili has several apartments he rents out.
