This is a beautiful event, in town,  most of it along and inside (swim) the Danube river. Swim is fast, only one loop linear and perfectly signed by frequent buoys. No real current sicne it occurs in a side bay of the river. The rolling start might work for some, like me, as long as one positions him/her self in the right wave time. Transition is fast, close to swim exit and to bike exit. Bike course consists of 2 loops of a pancake flat course, along the river with a little uphill to the castle. The scenery, if one manages to look, is beautiful and historical. Very fast T2, and the run consist of 4 laps of a back and forward along the river, completely flat. Very HOT this year, and hard to run in those temperatures, but it might vary from year to year. Plus there were showers and cold sponges and drinks twice per loop!

One has to plan how to get to the start in the morning since all roads are closed and the cars can only drop you 1km away. I strongly reccomend this race.
