About This Race

The 47K Relay transforms the demanding Tenerife terrain into a shared adventure, allowing teams to divide the challenging volcanic landscape and significant elevation changes between multiple runners. This format makes the substantial distance and technical terrain more accessible to runners who want to experience the island's dramatic transitions from coast to high altitude without committing to the full solo effort. Teams must coordinate their handoffs while navigating the same unforgiving volcanic rock and altitude changes that define the longer distances, creating a strategic element alongside the physical challenge.
