Marathon BikeErg

The Marathon BikeErg is a long-distance conditioning effort on the Concept2 BikeErg. It trains your aerobic system and the muscles that drive a cycling motion, mainly the quadriceps and glutes, with help from the hamstrings and calves. Because the distance is long, it also challenges your posture, pacing, and mental consistency.

Set the seat height so your knee has a slight bend at the bottom of the pedal stroke. Sit on the saddle, plant both feet on the pedals, and grip the handles with your hands wider than shoulder width. Keep your chest up, shoulders relaxed, and your upper body quiet before you start to move.

Begin pedaling with a smooth circular stroke. Push down through the ball of your foot, sweep back at the bottom, pull up lightly, and drive your knee forward at the top. Once your rhythm feels steady, add the arm push-pull so the handles move opposite your legs in one connected motion. Try to hold a steady pace or split for the full distance rather than sprinting early and fading. Relax your grip, keep your heels down, and let your legs do most of the work.

Breathe in a rhythm that matches your cadence, using your belly and sides to stay braced without holding your breath. To make it easier, lower the damper setting or shorten the workout distance. To make it harder, raise the damper slightly or aim to keep your split more consistent in the second half.

Fault: You stomp the pedals in a choppy up-and-down motion instead of tracing a circle. Fix: Pedal in a smooth circular stroke, feeling each part of the revolution from push down to pull up.

Fault: You let your arms go rigid or stop moving while your legs do everything. Fix: Add the arm push-pull once your legs are steady, driving one handle forward as the opposite leg pushes down.

Fault: You start too fast and then watch your pace fall apart. Fix: Hold a steady pace/split for the distance, picking a speed you can repeat from start to finish.

Fault: You grip the handles tightly and shrug your shoulders. Fix: Keep your shoulders relaxed and your grip light, letting your legs and torso transfer the power.
