Climbing in the mountains is one of the most rewarding aspects of road cycling — but it can quickly become punishing if you make a few key mistakes. Whether you're tackling alpine switchbacks or steady ascents, refining your approach can make all the difference. Here are some of the most common errors riders make when climbing — and how to avoid them.

  1. Starting too fast
    Riding with a low cadence — pushing a big gear slowly — can feel powerful but it places excessive strain on your muscles, especially over longer climbs. Aim to spin at a cadence of around 80–90 revolutions per minute. This engages your aerobic system more efficiently and helps you manage fatigue better. A smooth, fluid pedal stroke will also improve your overall climbing efficiency.

  2. Using the wrong cadence
    Riding with a low cadence — pushing a big gear slowly — can feel powerful but it places excessive strain on your muscles, especially over longer climbs. Aim to spin at a cadence of around 80–90 revolutions per minute. This engages your aerobic system more efficiently and helps you manage fatigue better. A smooth, fluid pedal stroke will also improve your overall climbing efficiency.

  3. Poor gear management
    Leaving it too late to shift into an easier gear is a common oversight that can disrupt your momentum and spike your effort levels. Anticipate changes in gradient and shift early, ideally before your legs start to labour. Smooth gear transitions help you stay relaxed, maintain cadence, and avoid the dreaded “grind and stall” moment that can break your rhythm.

  4. Ignoring body position
    Climbing out of the saddle too often can drain your energy reserves quickly. While standing occasionally can offer a short power boost or relieve muscle tension, it’s not sustainable for long periods. Remaining seated is more efficient, offers better traction — especially on steep or uneven sections — and helps conserve strength. Focus on a stable upper body, a slight bend in your elbows, and a forward-leaning posture to maximise efficiency.

  5. Neglecting nutrition and hydration
    Climbs, especially in the high mountains, are physically demanding and can last for an hour or more. Waiting until you're thirsty or hungry is too late. Make hydration and fuelling a consistent habit: small, frequent sips of water and a regular intake of carbohydrates (such as energy chews or half a bar every 30 minutes) will help sustain your energy and avoid the dreaded bonk.


By avoiding these common mistakes, you’ll climb smarter, ride stronger, and enjoy the beauty of the mountains far more.
