Charles Stevens (18, from London) and Will Hsu (18, from Leamington Spa), are the youngest ever people to cycle the 10,000km Beijing-to-Tehran 'Silk Road,' having accomplished this in 120-days starting from mid-May 2016, during their summer break - with all donations going to the 'A Child Unheard' charity. It's an incredible story - two teenagers who have funded the entire trip themselves (working part-time jobs), with 100% of the donations going to charity (nearly £25,000 already raised via JustGiving.com).  You can also watch their video appeal on the website www.beijingtotehran.com, along with their blog from the trip and photographs.The 10,000 kilometers covered nine countries and took Will and Charles four months to complete, from May to September of this year, and over the 120 days the boys have climbed to over 4,000 meters while descending below sea level. Supporters have been able to keep in touch with the Beijing-to-Tehran duo and monitor their progress via their blog on www.BeijingToTehran.com, where they have also been sharing amazing photos and stories during their journey.
