Once the run is edited, you can't prove anything if you share it. There is no red flag that says "EDITED" to differentiate from an actual, unedited run.
I was tempted to let this go as maybe Mike would believe your assertion to be true and actually share the run. But he will never share this "evidence" so I will explain where you are wrong.
What you fail to realize is that there is other data associated with the run. Yes, the rendered page doesn't say "EDITED" and there is no flag for this.
But if you view the source of the page you can see the actual collected data. It is in JSON format and the object (window.np.baked_data) can be found in one of the script tags.
Amongst the data in this object are the waypoints and few other sets of data that is not modified when a run is edited. Now you can change the overall information (total distance, total time). But the waypoints don't change and therefore the actual distance can be calculated. But the distance isn't in dispute here since we know the map he showed is of the 5K course.
There is also other data for speed (for those nifty pace color displays on the map) and GPS signal strength (which they don't seem to do anything with in the display). Both of these are captured at regular intervals (10 seconds) so with this you can calculate the overall actual time (with in 10 seconds). And obviously, the speed information tells you how fast the runner was actually going.
You can fudge the summary, but you can't fudge what was collected. So if the run was posted, it would take less than a minute to verify it. If anyone wants more specific examples I would be happy to provide them. And if by chance the actual run does make it to the web and you are lost on what to do; just right click the page and select "View page source". Save that text to a file. You can then pass it along to someone that knows what to do with it.
