That’s me going straight past the refreshment stand – yellow/red jersey and blue shorts.
I’ve noticed that much more power can be applied when the coordination is correct – that is – the hip moves backwards as the foot pushes forwards. The power comes from a re-alignment of the body to focus all the power through that hip joint – exploiting the hamstrings and glutes to extend the hip joint and the quads to extend the knee – combined with the core power from pulling up strongly with the other leg using the psoas, hamstrings and calves to flex everything on that side. The problem is that so much power goes through the knee that it can start to cause knee pain. I guess that when pushing big gears with lots of power this is something that might be expected – so increases should probably be made gradually. I only get very slight occasional twinges at the site of an old but serious injury – nothing more than that.
