Dude if she hit 495 I'd give her props. I didn't believe the claim when I heard it. Still don't (I think the BF told her she did and she believes/ed him).
Not the record clearly nor do I buy her 53:53 business. But it does sound like she came close.
495.3 miles is the best scenario calculation of what Amy Hughes did based on the videos available with a decent amount of benefit for her in the calculations. If we get all the videos and we see her average speed asymptote to about 3.45 mph like I theorize from her 12 hour videos, then the mileage she actually did could be as low as 476.1 miles based on 20 hours of activity per day. And it could be as low as 455.4 miles if we use 19 hours of activity per day from her claimed range of 18-20 hours per day.
And it could be much worse if the other live stream videos show more cheating at night.
I believe Amy Hughes was fully aware of what was going on and the numbers she is claiming since in the Sarah Williams podcast, Amy shows she knew she was not on track to break the record going into day 5 and then she claims to have done several fast 5k/10k runs at night the following two days to get ahead of the record. Those kind of multiple miracle fast runs just doesn't happen without the runner knowing.
