The first time Naumburg oragnized this event was back in 1953 since then, it's become an international fixture in the racewalking calendar. Naumburg is a small town located 50km west of Leipzig, I've never visited it, so I'm looking forward to exploring the place and drinking a pint of a gold old German beer, after covering the race obviously. This year they are holding a 50km in addition to the regular 20km. More details about the race can be found here: Race Manual
The track is a circuit which is 1 km long and takes you along an alley covered with big trees, so on a sunny or rainy day you are going to be bit covered. The track is flat and has one big turn which takes you around a roundabout and the other turn is a bit tight. Overall a good track, sometimes they extend the track for 1 km and make it two.
