I feel a slow ache starting to make it’s way up my legs.
I look down at the timer – only 1 minute and 30 seconds have passed.
Already the internal dialogue has started….
“Maybe we should just keep it at 7. I haven’t trained endurance for a few weeks – I should probably ease into it.”
1 minute 59 seconds.
Almost of it’s own accord, my finger punches the up arrow until the display reads “intensity level 12”.
“Don’t give in. You’ve done it before – and more – you can do it again.”
My feet move faster, climbing, up, up, up…endlessly upwards.
It’s no longer an ache – now it’s an outright burn. My legs are on fire. Yet I let go of all support, and increase the intensity to level 13 – forcing my legs to keep up, even as my breath begins coming in ragged gasps. My heart feels as though it’s going to explode. The seconds are crawling by. Time is at a stand-still.
