I assume if Guy is doing it, there will be a TV crew tagging along ?
Novel idea, he might just be doing it as an ordinary person for fun? It’s not exactly an expensive undertaking (compared to renting a warehouse and building a massive wall of death for example) so maybe doesn’t want/need a TV crew following him in return for footing the bill.
Also, dunno if the TD is the same but TV crews are against the rules of the HT550 as they constitute a sag waggon. I guess because you could travel light/fast and rely on them if the excrement hits the fan, so even if you never use them you’re taking less gear (or using lighter wheels, not taking a first aid kit, etc).
NOTE: A time trial completed with friends, family or media following the ride, effectively acting as a sag-wagon, is not a true self-supported effort.
