we will need to refer to this in idit 2021. so perhaps a mod will start a sticky post for this year's special race rules ?

Three mandatory layovers:
24-hour at any official checkpoint between the Skwentna to Iditarod stretch, including Skwentna or Iditarod. Must be taken before going on to Flat for the return.
8-hour at any official checkpoint between the Rohn to Rohn stretch, including either Rohn stops. On a normal route, this would have been taken between the Shageluk to Kaltag stretch.
8-hour at Skwentna on the return trip. On a normal route, this would have been taken in White Mountain.
