Preparing to race as a pair

Registration and accompaniment rules vary by race and category. Before preparing for a marathon, consult the organizer and a club or support organization to identify the arrangements suited to your situation.

Check the current conditions for runners and guides directly with the race organizer.

How it works: tether, voice, and equipment

The connecting tether

At the heart of the system, a braided tether approximately 12 to 20 inches long connects the runner's wrist to the guide's. Flexible but strong, it conveys direction through subtle changes in tension. When the guide pulls left, the runner turns; when the guide accelerates, the tether tightens slightly. Through training, the pair develops a tactile language that is almost invisible to outside observers.

Voice communication

“Small hole on the left in five meters.” “Mile marker 12 in three steps.” “Aid station on the right; I'll get you a sponge.” The guide speaks continuously and calmly, with exact precision. The runner says little to conserve breath but must be able to report pain or ask for water. Some pairs establish a short code: one tap on the tether means slow down, and two taps mean they need to talk.

Required and recommended equipment

  • A distinctive guide bib supplied by the organizers and marked “pacer” or “guide.”
  • A fluorescent yellow vest to remain visible to other runners.
  • A double hydration belt to carry gels and water for both partners.
  • A phone, required in case of a medical emergency.
  • Sunglasses and a cap for runners sensitive to residual light.

Preparation: physical, mental, and shared

Physical preparation

Training is the same as for a sighted runner, with a few nuances. Step cadence is often slightly higher because runners shorten their stride as a precaution. Long training runs of 17 to 20 miles should be completed as a pair to refine communication. Track intervals help build speed without the risk of obstacles.

Mental preparation

A blind runner must accept trusting the guide completely for 26.2 miles. Any tension increases fatigue. Several coaches recommend visualization, controlled breathing, and even meditation to help runners let go.

Preparing as a pair

This is what separates a novice pair from an experienced one: at least six months of shared runs before a marathon, a halfway test at a half-marathon, and a systematic debrief after every long run to adjust communication, hydration, and the handling of climbs and descents.

Other accessible marathons around the world

  • For another race, ask its organizer about registration for the runner and guide, applicable rules and available support. Arrangements for one edition do not guarantee those for the next.

AI for training: Strava and Lumyeye Pro voice Maps

Applications can help with preparation and reading information before or after a run. They do not replace a guide, mobility aids or the safety arrangements suited to the runner and the route.

Strava

The leading performance-tracking app supports VoiceOver and announces pace, distance, and time aloud. Strava segments let blind and sighted runners compare their performance on defined portions of a route.

Lumyeye Pro voice Maps

Lumyeye Pro can open a requested route in Google Maps, which then provides its own directions. This does not replace a guide, a white cane, mobility training or checking the route, and must never be used to decide when to cross a road.

Lumyeye Pro Vision Live

The Vision Live travel mode streams the camera's video feed in real time and answers spoken questions on demand, such as “What's in front of me?” or “Read this sign.” The AI does not describe anything spontaneously; it is an on-demand assistant, not a continuous narration system. Vision Live is a visual assistant. It does not replace a guide or cane during a run and must never be used to decide when to cross.

The spirit of partnership: beyond sport

What stands out in every conversation with these runners is less the athletic performance than the quality of the human bond. The marathon becomes a reason to form deep friendships, spend hours talking on long runs, and develop a kind of trust few sporting experiences share. Guides often talk about the return they receive: they gain as much as the blind runner.

Several organizations recruit volunteer guides throughout the year. You do not need to be an elite athlete; you only need to be faster than the runner you accompany and bring some humility. To learn more, contact AS Course Paris or the French Athletics Federation's adaptive-sports commission. If you are blind and tempted by the adventure, most major marathons offer pairs a free or discounted charity bib.

To prepare for another edition, consult the race’s updated information and build experience gradually with your guide and the professionals supporting you.
