Just watched Phily's video.
I thought the start seemed genuine until she said they could play it safe and run 2.24/25 but would rather take a swing. She must have known running her PB time on a slower course and a women's only race is not playing it safe! Overall, the start seemed to capture bits of authenticity.
The embrace the grind section at the end with Phily's from the grave voice-over of her pre-race aspirations (clearly recorded after, though) and daring to take a swing was a crappy edit too far!
