Is there anything else you would like to add?
Small points that should not draw away from the fact that this was an excellent trip and highly recommended by me and my fellow travelers from Iceland:
A better organized supply route for beer and gin in Tamil Nadu and keeping a small icebox in the support car stocked with instant coffee would be appreciated by many (invaluable on prior trips in India, Sri Lanka, Burma, Cambodia and Laos).
For some travelers it is more interesting to see wildlife, curiosities (snake charmer) or small home industry (the rope "factory" on the way to Kochi) than to many temples.
Finishing in Kochi should perhaps be optional as this town has nothing of interest for many (after biking through more interesting cities and villages) and created difficulties for those who decided to end the trip by relaxing on beaches (Varkala, Kovalam) 170 km south of Kochi. Perhaps finishing in Varkala should be an option.
