Stop with the accomplice theories, at least in terms of a runner carrying Rossi's timing tag. The finishing times are far enough apart that it is certain that no finisher carried Rossi's timing tag across the finish line for him.
If there was a photo showing Jake approaching or crossing the line, it would likely rule in or rule out Rossi as a runner, since Jake finished with a time just behind Rossi's purported time.
The photos made available on this thread make it more likely than not that Rossi cheated at the Turkey Trot, but unfortunately, as of yet, none are conclusive. However, when the available photos are considered in conjunction with Rossi's lack of social media in advance of the TT and with his immediate post-race social media activity (almost just as quickly deleted when his time was posted), it is a near certainty that Rossi cheated once again.
If Rossi is back to "running," the difference this time is that he cannot steal the Brojos' money. He has to give them notice in advance of any race where he has a chance to meet one of their challenges. They will have someone there to photograph and/or video the race and Rossi will fail.
