I guess that'd be enough time to do the ride, especially as you're not doing Calais-Paris which is the route my ride took. I did it as part of a 24 hour charity ride with about 150 other riders in a team of two so we did sections of it tag-team (one on the road for 2 hours/35miles, the other on a coach going to the next transition stop).
Just from a quick google, London - Newhaven is about 60 miles and Dieppe - Paris is around 110miles. Both of those distances are do-able in a day if you've done a few longer rides before. If you wanted to get it out of the way quickly you could leave London in the morning, get to Newhaven in the afternoon and then get an over-night ferry crossing. From there you could ride Dieppe-Paris in a day (a little less than the distance of the Dunwich Dynamo).
If you wanted to break it up you could have 3 days of about equal distance 60ish - 50ish - 60ish which would be much more relaxed and give you plenty of time to be where you need to be if you end up booking things in advance.
Are you riding back or getting the eurostar? Have a look at the bikes on eurostar thread if you're going that route..
