There is a location page at SpotWalla.com:
2019 Iron Butt Rally 2019-04-13 2019-06-28
but it's password protected.
Is that an IBA page?
Cheers,

The Iron Butt Rally supports several Spotwalla pages. There are pages for the riders and their families, the staff, and for the general public. The latter shows locations, but does not identify the specific riders.
In the past, there have been "time lapses" produced, showing the riders leaving the start/checkpoints, scattering to the four winds, and reassembling at the next checkpoin/finish. Very entertaining!
