Cranking my way up After Burner towards Power Up track, my mental moaning rises to just behind my forehead, trying to get in the way of my frontal lobe duties that are keeping watch of the trail, interpreting the bumps, variations, shadows and light. The frontal lobe is as much under load as my quadriceps are as I seek to retain a regular rhythm of strong low-cadence pedalling in a tough gear up the steep inclines.
