Running is a universal language that speaks to hope, discipline, and unity. I am very excited to return to Brazil where I won my first Olympic Gold medal. Each continent has its own spirit, and I look forward to sharing this journey with South America while inspiring people to believe that No Human Is Limited. See you on the streets of Porto Alegre on 12 July at the NB42k!#no human is limited# http://t.cn/AXVWHR4j
