Just got back to London after 750 miles on the bike. Left paris at 13:00 and rode south to check on my house 250 miles south of Paris, then turned around and rode all the way back to London. Bike never skipped a beat. South of Paris it was -2 C.
The ride is: 1.5 hours from London to the Eurotunnel, 30 minute crossing, 3 hours in France. All told, normally about 250 miles each way. If the weather is bad than 20 minutes on each side can be added, and if you hit either london, or Paris at rush hour, another 30 minutes. (These days it seems like it's always rush hour in London...)
Take care and ride safe,
