Cold weather, darker evenings and icy pavements can make winter running a real challenge. But your progress doesn’t have to freeze. Training indoors on a Wattbike Proton helps runners maintain momentum during the colder months, building endurance, strength and running form in a safe, controlled environment. Cycling also reduces impact on joints, giving your legs a break from constant pounding while keeping your aerobic engine firing.
If you’re new to cycling as a runner, shifting from seated to standing pedalling can feel awkward at first — just like adjusting to hill sprints after weeks of flat training. It takes time, but persistence pays off. Focus on the balance between resistance and cadence. Finding the right combination creates a fluid rhythm that makes winter Wattbike sessions feel natural and effective.
When you ride out of the saddle, you’re often working close to your functional threshold power (FTP). These efforts should be short, similar to interval sprints, while most of your indoor winter cycling should remain seated at a lower intensity with longer intervals. This approach preserves energy, builds an aerobic base, and avoids over-fatigue during months when recovery is already challenged by colder weather and lower daylight.
Getting your Wattbike setup right is key to making winter cycling complement your running form. Here’s how to adjust each element for the best results:
For an optimal running posture, set your saddle on the higher side of the cycling range. Aim for a slight downward point of the toes — just past horizontal — and ensure your knee almost straightens but never locks out. A knee angle of 145˚–150˚ is recommended. Watch your pelvis: it should barely shift side to side. If it rocks noticeably, lower the saddle slightly.
Most runners benefit from moving the saddle forward to better align the body with a running stance. Try to keep the saddle nose vertically in line with the bottom bracket. Taller runners may find moving the saddle slightly back more comfortable, while shorter runners often prefer it forward. Adjust until both seated and standing pedalling feel balanced and natural.
To mimic a running posture indoors, set the handlebars higher than the saddle. This encourages a more upright position, keeping body weight centred over your legs during out-of-saddle efforts. Lower bars will shift more load into your arms — sustainable for short bursts, but less comfortable for winter’s longer training blocks.
Handlebar distance varies by height and comfort. Taller runners may prefer the bars positioned further forward for a slight lean, while shorter runners usually benefit from a closer reach. Adjust until your position mirrors your natural running stance, letting you ride efficiently without strain.
Ease your cadence down over 5–10 seconds when standing to keep transitions smooth.
Use the right shifter to gradually increase resistance, aiming for 60–75 RPM.
If you’re above 120% FTP, shorten the interval and build stamina over time.
Winter doesn’t have to hold back your training. With the Wattbike Proton, you can replicate running posture, protect your joints, and continue building fitness from home — no matter the weather outside. By fine-tuning your setup and embracing indoor cycling, you’ll enter spring running season stronger, faster and ready to perform.
