Horseman 9: Ride From Van Horn To Blackwater In Less Than 17 Minutes Without Touching Any Water.
You will need to complete “The Wheel (Epilogue 1)” as a prerequisite, and the rewards are 150 Stamina XP and $20.
To complete this challenge, you can use the horse you get during the game’s first mission.
To make it easier, you can break and use the White Arabian.
As shown in the image, you will need to reach the area and roam around until you find the white horse, then jump on it and break it.
Before starting, make sure to have at least a couple of Potent Horse Bitters or Stimulants.
Blackwater and the south part of West Elizabeth are not available until the end of the first mission of Epilogue 1.
You can use a glitch to visit this area early in the game and complete the challenge before that mission.
You have to be careful not to fall from your horse or dismount; otherwise, you’ll have to start it all over again.
To avoid touching any water, you can start riding north to reach the bridge in Butcher Creek and go to the other side of the Kamassa River.
To go through the Dakota River without touching the water, use Bard’s Crossing, the train bridge from Flatneck Station.
To go through the Montana River without touching the water, you need to use the Owanjila Dam.
