AMAZON Summit to Sea

The team is to travel from Volcán Chimborazo glacier summit to Belém in the direction in which water flows. We must stay as close to the waterway as possible but, we can make any ascent within the gully/valley/glen/basin of the stream/tributary/river. If in making an ascent, we deviate and are thought to be out with the gully/valley/glen/basin that our river has flowed into, the journey must recommence from any point/or behind such point from where the deviation was made.
