We will walk/run the Marathon at Huangyaguan, 3 hours northeast of Beijing. We are on the Wall for 3.5 kms. We will have a practise run prior to the Marathon. It is expected to be warm and humid in the valley and cool on the mountain. We will begin the walk/run early morning to avoid the heat of the day. Water stations with bananas and electrolyte drinks will be available. Getting excited!
