I'd like to take a one day biking trip in Amsterdam in October, when I will be coming there for a conference. Could you recommend a scenic path/trail I could take? Please, if possible, include bike path numbers so I can look them up in my map.
I'm a fairly fit cyclist, so length in the area of 50-60 km should not be a problem, especially considering there aren't many hills in the Netherlands :-).
If you can, also recommend a bike rental which rents sporty bikes as opposed to the usual city bikes most dutch people use.
