At which time of the year you drove this path? We plan to go there mmid of March and wandering if surroundings of Barcelona is good location for bike driving at thant time of year...
Typically, I am touring around Barcelona during Dec, Jan, Feb. Marts is great for touring in the region and along the coast. It can still be cold inland (around 0 degree in the morning) and in the Pyrenees, but also 20 degrees during the day you never know in early spring, but Barcelona and coast is good all year.
