Here’s a challenge: Bike from Calais to Ieper — the terrain is flat as a pancake — visit battlefields and cemeteries, experience the Last Post ceremony at the Menin Gate.
Then you ride on to Brussels, where the terrain is more like a waffle.
It sounds like an awesome adventure. And it’s in June, so you have plenty of time to work on your quads.
Hey, this could be you! (Bombed-out village not included.)
