Touring on a fixed

I'm planning a tour from Paris to Amsterdamn next summer. I'll definately be geared though.

Will be my first touring experience.

How many miles a day would you normally plan for? I was hoping for between 100 and 120, is that too ambitious?
.

one week too late, yes it's too ambitious, I'd start off with between 75-80 miles a day, remember you're touring, not racing, just sit back and enjoy the ride, trying to keep up to 100-120 miles can take the fun away.
