Lucky you!!! I'd love to go to Iceland too. I hear it's fantastic. But of course not as wonderful as Norway (but I may be slightly biased, being Norwegian myself).

Where to go in Norway depends on what you like to do (besides riding your bike). Definitely have a look around Oslo and check out Vigelandsparken, a sculpture garden in the center of town. Great sculptures and a very nice park. And if you like history stuff, check out the Vikinship musuem. It's just a short boat ride from the town centre.

As for other places to go....I'm from Trondheim, so I would opt for going home. It's a very nice little town (although big by Norwegian standards) with a beautiful Cathedral in the town centre. And if you head that way, send a PM to Duck on Wheels and I'm sure she will put you up for a few nights (I would if I was there and she's my mom...).

Along the train route from Oslo to Trondheim, another place I would recommend stopping (although that would require a few PMs/phonecalls to make sure it's ok) is a farm in a village called Kvam. The farm belongs to some friends my family, great people (although a bit on the strange side in a nice way) and a fantastic farm. And they have a sauna higher up at their summer farm. Great place to spend the day relaxing! I have taken a number of friends to visit this farm and they have all loved it.

If I was taking you on a tour of Norway and you only had a week, that's what I would do. There are a few other Norwegians on the board (including my mom) so I'm sure you'll get more recommendations too.
