Who'd have thought it? Not my husband (aka doubting Thomas) certainly. My last run this morning was over frozen stubble fields and ankle-twisting ruts so I am not going to beat myself up for not beating records, but i kept running and even speeded up towards the end. I am having a cardio-respiratory exercise test this afternoon just so i can proceed with confidence to the next level. Maybe at my age I should have done this so start with, but they couldn't fit me in! Has anyone else completed one of these? I am more nervous about it than I was about running. Apparently they make you cycle until you are ready to fall off the exercise bike. Or is my son just trying to scare me?
