I also just got back from Austria. We travelled with/through Deepak’s group. He is somewhat difficult to get ahold of, but when you do, he is VERY helpful. He likely won’t be able to give you any info for awhile, as he doesn’t firm up his plans for the coming year for some time (at least that is what he told us).
Beautiful place, amazing scenery. As for “tips” it depends on where you are travelling from and how much time you have. Some guys we knew going over went on to France for the tour. We came back to the states after the race. During pre-race week, my wife did a day trip to Salzburg, which she said was great. If you are travelling with a spouse/non-racer, they may be interested in something like that. If that person wanted to take a 2 day trip, the options are endless (via train/car or plane).
As for travel there, go early enough so that if your bike does not make it to Klagenfurt (which we were told happens often, as the prop jets to the airport are not equipped for many bikes), you will not freak out when it shows the next day.
The course is great. Even the 3 lap bike is not boring. Water is clear and clean enough to drink. Sighting the first loop in the swim is not really possible, as the churning arms and legs prevent you from seeing anything. As for the 2nd half of the swim, go practice it in advance - where to sight/swim. It will make it much easier. ON the bike, BE PATIENT. I rode like a grandmother on a cruiser (even on a steep bike with a disc - which I would do again). I can’t believe the # of people that I saw walking early in the run. If you are from the US, accept the fact that Eurpoeans are more prepared than a “typical” US first time racer. You will not see nearly as many people who really expect to finish in 15-17 hours. This manifests itself in fast bike times but like I said, there were lots of walkers. Be careful with gearing, and ride the steepest hills you can train on in the middle of your training rides to mix things up. Learn to enjoy and get energy from the crowds.
The run is flat and partially shaded. This sounds embarrasing for some, but as I went with a bunch of dudes from the US, I was surprised when they got confused by the kilometer (as opposed to mile) signs on the run. Lots of my friends lost track of nutrition becasue of it.
The food there was some of the best and some of the worst we’ve had. No one is in a hurry, so be prepared for slower than what you expect service in restaurants. That said, the region relies heavily on the race for $$, and I found 95% of the local residents were overjoyed to have visitors and were very helpful (and I know 5 german words).
Feel free to shoot me a message if you want specific info
