Cycle Challenge Itinerary

I am using the itinerary as quoted from the Discover Adventure website here (its a PDF by the way) but to summarise what I'm letting myself in for:

Tuesday 19th June
Set off down south from home/work by train to London staying somewhere (I don't know where yet) near Greenwich (starting point).

Wednesday 20th June (early) Greenwich - Dover - Calais
Set off towards Dover, leaving early to avoid the traffic, not because of congestion but to avoid being knocked down I guess :). Heading towards Canterbury then through the North Downs onto Dover, for an evening ferry to Calais, where we will be staying the evening.

Thursday, 21st June - Calais - Abbeville
Head out south west towards the town of Abbeville, going through the market town of Guines, passing Desvres, heading towards the Canche River, then onto Hesdin, which is near the historic site of the Battle of Agincourt, heading down towards the river Somme, then onto Abbeville.

Friday, 22nd June - Abbeville - Beavais
Heading out of Abbeville, towards the town of Amiens, then onto Beavais through farming hamlets and most of the riding is on flat roads.

Saturday, 23rd June - Beauvais - Paris (Eiffel Tower)
Heading south again towards Paris, the route takes us towars the town of Meru, and then onto the suburbs of Paris, notably St Denis. After going through the suburbs we hit the river Seine and follow the northern esplanade, in the shadow of the Bois du Bologne until we reach Pont d'Iena and then onto the Eiffel Tower and the finish.
