Horseman 4: While Mounted, Drag A Victim For 3,300 Feet Using Your Lasso
You will need to complete Chapter 1 as a prerequisite, and the rewards are 50 Stamina XP and $10.
This guide will let you know how to complete the Horseman 4 challenge in Red Dead Redemption 2.
To avoid losing honor, you will need to attack an enemy camp or gang hideout and kill everyone except the last enemy. You can use the lasso and start dragging him.
Don’t worry about your victim’s health, alive or dead; the challenge is still valid as long as you’re dragging him with the lasso.
