It's without doubt the most well organised race of all the IM races I have done. Bar Kona (which I've only heard about second hand) I can't think of another race that has such a well organised event. For example, you get a travel permit for your stay, so that you can zip around on the trams free of charge, there are buses to take you out to rack your bike, whilst racking, you have a helper to talk you through the whole thing. You then get the (free) bus back again. The year I did it was very hot, so there was a water station at the bus stop. On race day, once you have finished, you get another helper who walks around with you and makes sure you are ok.
