You start this quest by Talking to Samu, south of the village of Bayen. He only appears there after 'Starvation' has been completed. He offers you a race, if you pay him 50 auras. the race itself is very easy, and can be finished with 2 minutes remaining if done properly (keep your horse's meter in full green, though not red) and jump over obstacles. you don't have to dismount to grab the pints. You'll get the deed to the savannah house, some auras and other useless items.
