Klagenfurt where the race is held is not the msot inspiring town, thankfully the race ie held in the lake about 5 Kms from the town centre, accommodation is plentiful near the lake , best to search through the various information sites as opposed to using the official race hotel.
The swim was a huge fight last year 2200 people, it spread by the time you hit the beach after 2km for a 40 metre run, the last 800 metres is up a canal with spectators either side which was awesome.
The bike is three loops and it is FAST, three years ago I managed a 5.10 split, the first part follows the lake and is flat with a couple of mild undulations, after about 20k, you turn off this road and start to climb, the first part is a long gradual uphill before you have a short respite into Ekyden where you turn left and meet the worst of the hill, at its steepest I was using a 39/25 on a blade and having to grind up, the steep section lasts 800 metres before it becomes another drag to the top, then it is very fast downhill for 4km, then you need to keep the legs spinning to keep the speed up as the lap come to an end by the lake, repeat another twice.
The run is on a mixture of pavement , loose track with a few grass areas, you head south from the transition and go through a couple of public beach areas, then the run turns along a railway line ( no supporters, lifeless) before heading back towards the transition area, it then heads back to the canal and heads into the centre of the town , before heading back, this is and out and back part of the run, it is two laps.
Organisationally it is pretty good, although there were a few things that went wrong last year re the pasta party and awards dinner, the expo is OK but not spectacular.
Hope this helps, friends and I will probably head back next year
