For those who have raced there or are going and have knowledge of the place, I have a few questions.
1. Looks like most bike bags and carriers are too big for Spanish trains officially, but has anyone had difficulties.
2. Doesn't seem to be a lot of lodging in the city. Am I wrong, where did you stay?
3. I will be flying transatlantic. Lisbon or Madrid seem best. Adding a small hop to nearest Airport (Vigo, or Santiago} seems near impossible from Portugal, and expensive from Madrid. Seems like there is only one daily train from Porto and other trains from Porto require bus leg. Correct me if I am wrong.

4 High speed train ( still takes 4hours) from Madrid will not allow bike bag. Is this correct)
5 slow trainfrom.Madrid seems as fast as the high speed train.
6 seems like no cars are allowed downtown, but you probably have to drive to the race because there is not much lodging downtown.

1. Rented a car and didn't take the train
2. Reserved through air bnb
3. Flew into Madrid and rented a car
4. Not sure
5. Not sure
6. You can park easily on the outskirts of the city and walk to anywhere you need to go downtown.

Thanks. Did you have a bike bag? Any troubles fitting the bike or bikes in the car?
