The Undefeated Champ
South of Gerudo Town is the Sand-Seal Rally. You will see the recognizable platform marking a hidden Shrine, plus the orb. Try to approach it, however, and you will be told that it is actually a trophy for whoever can complete the Sand Seal race and break the champion’s record.
Speak with the Gerudo NPCs Shabonne and Tali and pay up 50 Rupees to race. You can save before this and reload your save if you want to save on Rupees. Once you start the race, you have to complete it in under 1 minute and 30 seconds. In addition to that, you have to go under all of the archways. The rules are that you cannot fall off your shield (i.e. you cannot crash into anything) and you cannot go off-course.
The course is not randomized, so if you fail the first few times, keep trying with your previous knowledge of what went wrong. The archways can become tricky to find, making it easy to go off-course. But if you time your dashes properly and don’t make any dramatic turns, swinging you uncontrollably, beating the champion’s record is easy.
You will first pass under some giant skeleton bones. You will then pass between two cliffs, where Lizalfos will push rocks at you. Avoid them so that you do not fall off your shield. Finally, you will pass through a network of three enemy camps marked by three skull-shaped rocks. Stay left and go up the hill and you will see the finish line. If you go right you will go off-course.
Once you have won, pick up the orb and place it in the pedestal. Doing so will reveal the hidden Raqa Zunzo Shrine and complete this Shrine Quest!
