Nasal strips for cycling: what riders are using and why

In the last few Tours de France you've seen it more often: riders crossing the line with a nasal strip on their face. No wonder — cycling is 90% a ventilatory game. Whoever controls their breath on a long climb wins seconds nobody else picks up without heart-rate data.

This article: what a nasal strip for cycling actually delivers — for pros, amateurs, and the Saturday club rider.

Where the ventilatory edge lives

Cycling spends most of its time in submaximal work — Z2 on the flats, Z3 on rolling terrain, Z4 on climbs, Z5+ only on attacks and finish sprints. Acute nasal breathing reduces ventilatory efficiency (VE/VCO₂) by roughly 10% versus oral breathing in healthy individuals (BreathWISE, PLOS One).

On a 5-hour road race that's a meaningful number. Not "10% more power" — but "10% less ventilatory cost across most of what you do that day". That shows up in the tank on the final climb.

External nasal dilator strips significantly increase peak nasal inspiratory flow (PMC review). For riders with mechanically restricted nasal flow — more common than you'd think, especially if you've ever broken your nose — that's direct gain.

By rider type

Pros and serious amateurs. Marginal gains. On a 200 km race, every ventilatory win is measurable. Many pros have used them since 2020+, especially on mountain stages.

Gravel and marathon MTB. Long duration, variable intensity, often on dusty trails. A nasal strip helps doubly: better flow + less unintentional mouth-breathing on dusty descents.

Club riders and Saturday cyclists. The win is more comfort than time. Lower perceived effort on long rides, mouth less dry.

Indoor / Zwift. Short and intense; oronasal dominates. Marginal win except in long Z2/Z3 sessions.

What Tour riders say

No official statistics, but from interviews and broadcast footage: multiple riders use nasal strips structurally. Not as a miracle, but as part of a marginal-gains toolkit alongside nutrition timing, equipment, and pacing.

Practical protocol for riders

Training rides. Wear a sport nasal strip on all Z2 and Z3 rides. Train your nasal breathing on the flats and light climbs.

Race day. Apply 10–15 min before the start. Clean, dry skin (no sunscreen on the nose bridge — apply sunscreen on cheeks, avoid the strip zone).

Long endurance rides (4+ hours). 12+ hour tested performance is the relevant property here. No mid-ride replacement needed.

What a nasal strip *won't* do

Not lift your FTP. Not raise your 5-min wattage. Not make your sprint faster. What it does: more efficient ventilation across the majority of your ride time, faster recovery between efforts, and easier nasal-dominant breathing on climbs.

The Hypowered angle

Sport nasal strips from Hypowered are built for long duration and heavy physical conditions. 12+ hour tested — a Tour stage comfortably within range. Sweat-resistant — no slipping on a 30°C mountain stage. Hypoallergenic.

For races where photos and helmets matter: the clear race-day variant — invisible under sunglasses, identical flow.

FAQ

Does a nasal strip fit under a cycling helmet and sunglasses?

Yes. The strip sits on the nose bridge, well below sunglasses and outside the helmet zone. Thousands of users report no interference.

Will a nasal strip come off in rain?

Hypowered Sport Nasal Strips are designed for high sweat load — essentially the same mechanical challenge as rain. Applied correctly on dry skin before the start: stays on.

Does it help at altitude?

At altitude oxygen pressure drops; nasal breathing helps extract as much as possible from each breath. A nasal strip helps mechanically — no replacement for altitude training or acclimatisation, but a support.
