Once again you need to race your way to victory, and you must finish in first place to complete the mission. Thankfully, you’re not burdened with a cart, simply race on your own horse (for maximum stamina) instead.
You can’t shoot anyone or knock anyone off the road, so as long as you can get to the front of the pack quickly - preferably at the start - you shouldn’t have much to worry about. This is a much longer race (compared to the last one), so it’s very much about getting the running rhythm right.
Always keep a close eye on your map and also on your horses stamina level. Even with a methodical pace, it’s surprisingly easy to drain it away without realising if you’re not careful. You’ll need to pass over a total of 28 checkpoint fires to reach the end.
As long as you’re paying attention as you race, coming in first place should be a piece of cake. This also signifies the completion of all of Mr. Dickens’ missions.
