Para alpine skiing at the highest level runs at 100 kilometers per hour through terrain that changes every few seconds. For athletes classified as visually impaired, none of that is visible. Their guide skis ahead of them by roughly two to five meters and delivers the course through a radio system embedded in the athlete's helmet: which gate is coming, how tight the turn is, when to load, when to float.

What Veronika Aigner did at the 2026 Winter Paralympics shows how the system works and what it demands. Her regular guide was injured six weeks before the Games. She competed in Cortina with two people she had been training with for weeks, not years, and won four gold medals and a silver. That performance reveals both the sophistication of the guide system and how much a skilled VI athlete can adapt when the system is disrupted.

What Guides Do on Course

The guide's job breaks into two phases: course inspection and race delivery.

Before any competition run, the guide skis the course, memorizes it, and builds a call sequence. The calls are standardized across national programs, with some variation: "turn left, easy" means a wide turn; "hard left" means a tight one; "straight" means load and push; "glide" means stop generating power and carry speed. The sequence is rehearsed until it runs without hesitation. During the race, the guide delivers it in real time while skiing at competitive speed, because the distance between guide and athlete has to stay consistent to remain useful.

The radio system runs one way, from guide to athlete. There is no back-channel. The athlete hears the calls and responds; the guide reads the athlete's positioning and adjusts the delivery pace. In a super-G run that takes 90 seconds, a guide makes roughly 60 to 80 calls.

The athlete's job is to respond to those calls without hesitation. A hesitation at 90 kilometers per hour costs time. A wrong response costs more. The decision interval between hearing "hard left" and committing to the turn is measured in fractions of a second.

How Athletes Learn to Race on Voice

A new guide partnership is disorienting in one specific way: voice recognition. When you race down a mountain with 15,000 people watching and crowds making noise on either side of the course, the only voice that matters is the one in your ear. Athletes describe learning a new guide's voice as something that takes real time to trust: not just the sound of it, but the rhythm, the timing, the way they signal a tight turn versus a wide one.

Top VI athletes can switch guides and remain competitive, as Aigner's result demonstrates. But most coaches and athletes describe guide familiarity as a genuine performance variable. Partners who have raced together for years have calibrated to each other in ways that are hard to articulate: the guide knows when the athlete is carrying speed and compresses the call window; the athlete knows the guide's pacing cues well enough that the calls become confirmation rather than instruction.

Jake Adicoff and his guides in para cross-country skiing work in a different format, but the principle is the same: the partnership is trained, not assembled on race day. In cross-country and para biathlon, VI athletes ski with a guide on a short tether rather than at a radio distance. That physical connection means guide and athlete are communicating through the mechanics of the tether tension itself, not only voice.

How the Matching System Works

Guides are classified as B1, B2, or B3 to match the athlete's classification. A B1 athlete, classified as having no usable light perception, requires a B1 guide. B3 athletes have the least restrictive classification in the group and can compete with guides up to B3. The constraint exists to keep competition fair: a guide with more functional vision than their category allows would provide an advantage the system does not account for.

National Paralympic committees manage the matching process. Athletes may train with several potential guides before committing to a primary partner for a competition cycle. Guides compete under the same team banner as their athlete, are classified as athletes within the IPC system, and receive the same medals. When Veronika Aigner won gold in downhill in Cortina, her guide won gold in downhill in Cortina.

There is a pathway into guide skiing for able-bodied skiers who want to participate in para alpine programs. Most national programs run guide development courses, and many adaptive ski centers run recreational guide programs that are separate from the elite certification track. For a family where one person skis and another has a visual impairment, the recreational program is the realistic starting point: it covers the fundamental techniques, radio communication, and safety protocols without the full competitive pressure of the elite pipeline. The technical standard at the elite level is high: guides need to ski faster than their athlete, maintain a precise following distance, and deliver cues accurately under race pressure. The recreational tier is accessible and a meaningful way to participate in the sport alongside someone with VI.

What to Watch For

The next time a VI para alpine event is in your broadcast feed, watch the guide. The athlete is the one with the race number; the guide wears a matching bib and skis the course three to five meters ahead. Watch the guide's movement through the turns. The calls you can't hear are shaping every decision the athlete makes.

If you want a fuller picture of how VI competition works across events and categories, the para alpine skiing guide for Milano Cortina 2026 covers how the events are structured and which athletes competed when. Once you know how the call system works, the race is no longer just one athlete against the clock.
