I think he means the race in the Dampe's tomb.
A tip: Walk backwards and do sidehops. When you get hit by fire, keep pushing the Z button as Link will reposition himself in the right angle. Warp songs (that don't work in that place) can stop the timer for a few seconds.
What will be really annoying in the 100% blindfolded run are some of the minigames, especially the chest game. A 1:32 chance plus finding the chest in the room and walking back after you lose.
BTW the Lens of truth might be helpful in the desert. Activate it and target the ghost.
