Since 2012, GlobalLimits had been organizing multi-stage races in Cambodia, Bhutan, Sri Lanka, and Albania. São Tomé is organized in 2020 especially for qualified runners. Our goal is to combine running with local cultural appreciation – that is, all our race locations have spectacular historical backdrops and there are always opportunities to stay in local homes.
Our team, including our volunteers and local partners, are experienced runners or event organizers; we have proven track records in organizing successful multi-stage races.
Our professional medical team specializing in wilderness and emergency medicine will provide you necessary high-standard medical treatments during the race week.
