The costs must have been immense. You had to pay Faith, pay for all the new prototype gear, travel, lodging, and appearance money for every Nike runner and the Nike employees. They likely had been there for a few days to acclimate/set up. They had to rent the venue (which probably was rented out for a few days, including all of the staff at the venue), set up the extra equipment, contract out the A/V work so they could live stream everything. I am probably missing a few other items there.
For instance, I noticed during the introductions the number of Nike-affiliated employees/staffers there seemed crazy high. This wasn't a 10 man operation, it looked like there were at least 100 people there.
That said, even though Faith did not hit the time, Nike still gained a nice PR boost for the event.
In the writeup on the main page, the author wrote that no woman can break 4:00 right now .... I seriously wonder what would have happened if Faith had done this around the time she ran the 4:07 in race conditions. As has been commented on many times in other threads, Faith's fitness level and strength may not be as sharp as prior years.
Which all means, if she is able to have another solid year (perhaps 2026?), then I would certainly tune in to see her take another crack at it. I think we all would.
