Bouyed by my recent success in completing 5km using my jog/walk strategy and, with one eye on my first target of the season (Inter Services duathlon in April), I thought it would be useful to see just how fast I could run 5km. The idea was to get my legs turning over faster than they have done for a very long time, and to see what the effect was.
I have a very low boredom threshold so setting the treadmill at a constant pace and just running until I reached 5km was not an option. I warmed up by doing 30 mins on the gym bike at a respectable 32kmh (HR settled mid to high 140s), and then leapt off and hit the treadmill. I broke it down in to 5 minute chunks of 2 mins at 13.5kmh, 2 mins at 14kmh and 1 min recovery at 10kmh. 5km time was 23 mins 10 seconds. Very happy with the time but even happier that my cardio system coped really well; I was certainly breathing hard but always felt in control. My legs weren't so happy! They haven't been made to go that fast for an awfully long time but I think, mentally at least, I have made a break through. I will never be a 'runner', but I have taken a small step to 'running'.
