Well, fellow dryathlons, we have walked nearly 22000 steps today!! This despite spending hours on the batobus and using the Metro, so you can see that we've covered a lot of ground. Champs Elysees, Eiffel Tower, Tuilleries, Notre Dame, Ile de St Louis, several Christmas Markets, several detours when we got lost and/or left belongings in cafes, and back to our Montmartre base for a lovely meal and drinks. We're now back at the hotel with sore eyes and reeking of smoke - from the Parisians, not us! 
I feel for those of you feeling the heat now as Christmas rushes towards us. I'm going to be just the same once we get home. But for now, I'm going to enjoy the last self-indulgent day away from it all. 
It's so mild here, we've been sitting outside with coats off - how weird is that?!
