~10k easy run @ 6-6.5/km (9-10 km/h), trail-ish, forest paths mainly, avoiding hard roads if possible. Not completely sure about the distance yet, as my knee hurts a bit after last week's semi in Nice, so number of those kms can change slightly.
Starting off from under the tree on Porte de Boulogne roundabout (http://goo.gl/7D9JC) (linked map shows the exact meeting point) (near M10 Porte d'Auteuil) at 10:10 am sharp. Around 10 mins later I could be passing next to the tree between the lakes (http://goo.gl/maps/cKnDr) if you prefer to join there (near M9 Ranelagh), but please let me know in advance if you're planning to join there, as otherwise I might choose a different route.
Drop me a line/text on[masked] if it's raining heavily outside as I could get lazy then and decide to stay indoors instead (small drizzle is still fine though, snow too ;)).
