After looking up weather conditions for Chamonix and the surrounding areas, it looked like there might be a bit of rain to start the race. Then, today, we received the following email from the organizing committee:
Attention, weather conditions planned during the race: rain, wind and cold.
Provide the necessary equipment
Comité d'Organisation de The North Face Ultra-Trail du Mont-Blanc
Thank goodness Darin is prepared and packed for any kind of weather! And I don't think he ever was a boy scout!
