Getting to Circuit de Catalunya from centre of Barcelona?

[Thatch]

Lucky enough to be going to the Spanish Grand Prix next weekend, but trying to sort out transport to the circuit from our hotel in the centre of Barcelona on the three days.

Google Maps suggest 30 mins by car or 1 hour 45 mins by Metro/Train/foot!

Anyone done this commute in years past?

Options to me seem to be get a hire car or loose 2 or 3 hours of each day!

Thanks in advanced for any help.

Thanks for the 'Heads-up' on the bus service.

All booked!
