Tomorrow the four-day event starts with the mens junior ITT and the womens U23 ITT. Here's the course map.
And don't ask for profiles...
Entry lists for both events are available, the final start lists are yet to come:

I have no idea about the U23 women, but the junior ITT will be a Danish festival. Pedersen, Andersen, Würtz Schmidt and other Danes have dominated the junior ITT's this year. They can even leave a guy like Niklas Eg at home.
The EC website has information on all other events, too.
