#Causes: The Primary Source - Running the Río Marañón

I was sick; really sick. The kind of sick many people experience when traveling overseas, where your guts feel like there is something living inside them. Tom and I were on an eight hour van ride from Huaraz to Puente Copuma with two other class V kayakers to run the Upper and Inner Gorges of the Río Marañón in Perú, possibly the biggest whitewater I had ever seen.
