The longest surfing ride on a river bore was 17.2 km (10.6 mi), achieved by James Cotton (Australia), surfing the Bono tidal bore on the Kampar River, Sumatra, Indonesia, on 10 March 2016.
The height of the face of the wave was up to 8 foot at its highest, and was travelling at approximately 20kmph. The record attempt was to raise funds for the Human Variome Project, a project dedicated to sharing genetic data to save lives and reduce disease.
