London á Fontainebleau

I've decided at short notice to take two weeks off (easier than it sounds being unemployed) and go to Fontainebleau (south east of Paris) with a few friends to do some climbing out there.
We're going to be camping it up - so to speak - so we're taking turns with a trailer.
I, for one, have never cycled with a trailer before but am getting a bit of practise between then and now so I'm not concerned about that so much as the route we're taking.
As the most experienced cyclist of the bunch I've been designated 'Route-Guy'.
I've done a lot of touring using geared bikes around the UK and I've done the south-coast fixed a few times but never really toured outside of the UK.
The plan is:
Take a leisurely cycle down from Greenwich to Dover via Chatham, Faversham and Canterbury. Hop on a ferry across to Calais. Take the coast road (the D940) down to Abbeville then head inland staying west of Amiens, Cergy etc and once we reach Chartres we'll swoop east towards the forests at Fontainebleau in time for tea and medals.

We've got about 10 days to get there - climb and get back - with potential for Eurostar home from one of my light-weight compadrés (he needs a lesson in HTFU).

I read dr.oblong's thread about riding to Paris from Le Harve but that's not really the route we want to do if we can avoid it - A - because we don't want to go to Paris and B - because we don't want to go to Le Harve. Fact.

So - suggestions? Alternate routes? Roads to avoid? We're trying to avoid getting bogged down in towns and cities en route as it'll eat into climbing time so we're hoping that two long days of cycling will get us there from home to somewhere we can do this:

oh man, i am so jealous! i had a week in font recently & didn't want to come home! heh. i'd love to go back with a bike, but i'm not sure about carrying boulder pads. what sort do you have & how do you find transporting them on the bike?

2 days seems a bit ambitious - 200ish kilometres per day with a trailer?

Well the pads fold into a little box shaped thing about the size of the trailer (a bob yak) so we're lucky on that front. We've weighed the whole thing packed and I've had a cycle with it today (around Finsbury Park a few times and it's surprisingly mobile but I know that after 100k's I'll be feeling it...)

2 days though does seem a bit ambitious perhaps. Though having said that - All three of us are in good shape. I'm probably the least fit of the bunch, (one's a triathlete, the other swam the channel this summer!) We're hoping to get to around Boulogne-sur-mer by the end of the first day though if we can get further we will. I know that coast fairly well and the roads (though I've not cycled them) are flat and quiet from memory. Then the remaining part of the ride is where I get a bit lost. I'm not really sure about what to expect in the country west of Paris - hills? Main roads etc?

but are you gonna send eclipse when you're there!?

She will be mine. Oh yes. She will be mine...

Fuck me that's amazing! Been wanting to learn to climb for a few years, I must get round to it this winter.

I hope you send it man, have you been before? I'm going back in January gonna start trying Arrabesque (sp)
