If a tree falls in the forest.....

... And nobody hears it, does it make a noise?

Or put it another way.....

If an Issi runs a Sweatshop 5k run in a record-breaking 27 mins 34 seconds but forgets to switch her Garmin on, does anyone believe her?

Well, it doesn't matter, because a week later, the exact same Issi ran the exact same Sweatshop 5k run in the exact same time, and her Garmin captured every single aching, panting, swearing step.  

The gospel according to Garmin - I ran 5k in 27:34, and my heart exploded.  Again.
