Water Stops

Water stops are situated along the routes. Each water station is there to provide water to competitors and are equipped with basic first aid to help with minor medical complaints.

Wildlife Safety

The Tropic Air 10to4 routes run through alpine moors, indigenous forests and lowland savannahs so animals are likely to be seen during the race. When racing it is important to stay on the designated course and routes will be cleared ahead of the start. There will be armed rangers located around the course, however you will be required to sign a disclaimer (or a parent or guardian for those under 18) to race at your own risk. The utmost care will be taken to keep you safe on the course.

Emergency Procedure

  • The race operates in remote locations. If you are involved in or witness an accident, please report immediately to the emergency contact number (available closer to the event) or a water stop. Basic first aid will be administered at all water stops, and along the route by ambulances and sweeper cars.
  • For serious incidents, the Tropic Air helicopter will evacuate participants to Cottage Hospital, Nanyuki or to an airstrip, for onwards AMREF Flying Doctor medical evacuation pickup to Nairobi.
  • By signing the disclaimer, the participant agrees to all hospital or medical centre charges, and any ongoing medical expenses, to be the sole responsibility of the participant.

PLEASE NOTE – in an emergency, it can be very difficult to organise air-evacuation from health care insurers, even if you have evacuation cover. Without cover, air evacuation alone can cost $4,000 and must be paid prior to flight. One of the quickest and safest way to evacuate in Kenya is via AMREF You can purchase membership for the event for just 1,600KSh on your entry form.
