Riding around Munich is pretty uneventful in terms of terrain. It is pretty much dead flat for 70km south of Munich until you hit the small climbs at the base of the Alps. I didn't think that riding around Europe could get any flatter. Then I went to Belgium.
Belgium is flat, extremely flat. You can ride for hours on end and the biggest rise you will go over is a bridge.
Racing in Belgium is renowned for being for hard men and now I can understand why. With no hills in sight, speed is high and with very little to block the wind, riding at 50kph+ into a headwind is tough work. Combine that with cobble stone streets and hundreds of riders and you have some hard racing.
Below is the profile of a three hour ride in Belgium. The only rises we went over were three bridges. See if you can spot them.
