I have a bit of a chesty cough, and that in combination with the air pollution warning suggested that a run wasn't the best idea, so I set off for a 6km walk, wearing my Garmin so I could get an idea of pace. I was astonished., Forgive me if you've all done this, but the difference between running and walking is vast! My usual running pace is between 5.50 and 6.30/ km, depending on terrain and mood etc. I thought I was walking briskly this morning, but my pace was between 10.20 and 11.00/km. Nearly half the speed. I just hadn't realised how much faster even slow running can be. Hoping to be running again by tomorrow... I just don't have time to walk!
