After seven weeks, my internship’s come to an end and I'm leaving Bangalore tomorrow. From here, I'm taking the overland route back to London, travelling north through India and Nepal, over the Himalayas and across the Tibetan plateau, before I head along the eastern part of the silk route to Beijing. I'll then cross the Gobi desert and Siberia, before crossing the Ural mountains and into Europe. The full journey will be around 9,000 miles. I expect the trip will take around 5 weeks, which means I should be back in London around mid-September.
