Raison: Desynchronized audio issues (the first 9min are completely desynchronized). A few "splices" throughout the run, since the marathon organizers tried to catch up by resynchronizing the audio and video a few times (examples at 9:27, 15:58, 16:36, 45:24). Also, since there is no load remover visible on screen, I would have tried and retimed it to get an RTA time, but all these issues probably make it impossible to retime it accurately.
