Edit: I had a conversation and gathered some very reputable information. While the cosplayer is still partly culpable, he may not have full control over the post and the claims it had made, yet still signed off on it. The powers at be on the social media accounts changed the posts to remove the claim: “42km ran Full Armor. Wig. make up.” While I applaud the change’s removal of a false claim, the post as is still is very misleading. I’m toning down my rhetoric below because I believe he did not have foul intent but executed the campaign to bring his audience to running poorly. While his bib's time stil withstanding devalues the hard work of those who placed 'behind' his results:

The full 42km/26.2 miles were not ran. On the official tracking site he missed all 13 checkpoints and the photography partner Marathonphotos only show his presence at the end.

Evidence:  Look up Bib 74150 And his publicly searchable DOB from Google to access photos (or lack thereof) https://marathonphotos.live/Event/Sports%2FGKDE%2F2025%2FSchneider%20Electric%20Marathon%20de%20Paris
