Karma Enduro has an excellent website with all the details that you could want. So rather than try and re-invent the wheel, we suggest that you check it out. If for nothing else, because it is a great site!
Essentially, we fly from Heathrow. This true endurance rally starts from Mobor Beach, Goa and takes us 2,000 kms (between 6 and 8 hours’ driving each day) to Cochin, Kerala along the west coast of India, through routes rarely travelled by car - wild tiger reserves, ancient tribal, forests, through hectic Indian cities and over mountains. Each day will be different and the terrain will be a test of driver, co-driver and of the basic Ambi car.
