Thanks for Your answers.
I have just noticed this video:
Looks funny, its a pity all the bikers ride MTB but the amount of bikes gave me some hope
Maybe i will take my road bike, as I see the gears may be necessary.
Joao, what do You mean calling Coimbra unfriendly city? Is it becouse of the hills or something else (for example Warsaw is not so friendly becouse of the dumb drivers who does not give a shit about bikers)
I do have three questions more.
1) As I heard and saw (on the meteo graphs) Coimbra is fairly rainy (or very rainy in compare with Warsaw). Baptista isnt it difficult to ride a bike in Coimbra becouse of the constant rain? Excuse me if the question is silly
2) Bike in a train. As i get to Lisbon with a plane i will have to go with a train to Coimbra. Is it common to travel with a bike in train, does it require an extra charge, or maybe its fully banned
3) The Ocean
As I see Coimbra is only 40 km from the Ocean so i've already made some plans to go there for the first weekend. Does anybody knows the road? Is it fine? Is generally fine in Portugal to ride on a public roads with a bike?
