Planning to tour part of EuroVelo route 5 from my home in London through France, Belgium and Luxembourg this summer. I am quite keen to complete the trip on my fixed gear bike, I am not entirely sure if this is a ludicrous idea as I have never done any long distance cycling on a fixed gear bike.

Just wondering if anyone has toured fixed gear and could offer some advice for ideal ratio for touring, etc.. I am planning to put in 50+ miles per day, how difficult is this going to be?
