Today, I ran my staple brisk morning run, after allotting two days for rest and recovery from skiing and orienteering. My goal was to get in a fast, hard short run to shock myself back into training. Target pace was sub 5 minute kilometers, at which I succeeded, though only just.
My breathing rate was either 3 or 4 steps per breath through the first 5 km, then 2 or 3 steps per breath through the last leg. While this was intended to be higher intensity than normal, I still found myself huffing and breathing ineffectively. As much emphasis as I need to put on my conditioning and musculature, I need to devise ways to refine my breathing while running and increase my oxygen efficiency.
