Spartacus, Eat Your Heart Out
Once you arrive at the breech, you'll find several chariots lined up at the starting line. Move to the blue dot on your mini map to hop aboard your chariot and begin the race.
The race route will be demarcated by smoking campfires, similar to your first race with Bonnie back at the MacFarlane ranch. Your chariot controls much like any other wagon, watch the stamina bar of your horses while you're whipping them, but you'll have to be extra careful to not upset your lightweight cart.
At the count of three, the race begins. You may be tempted to pull out your revolver and dispatch other racers or their horses, but doing so will instantly disqualify you. You'll have to win this race fair and square.
The route is a twisted one, filled with tight turns, but fortunately your chariot handles like a dream. There are several sections where you have to choose between two routes. Take what seems like the most direct route, but don't worry too much if you end up on a longer section, you'll be able to make up the ground soon enough.
It sounds simple, but the best way to win this race is to get ahead early and stay there. Go as fast as possible, watch out for tight turns, and stay ahead of the pack to win easily. The race ends when you pass between the twin pillars on the plain.
After the race, a stranger offers to take care of the chariot, and Nigel suggests you leave the area quickly. Run over to his wagon and hop aboard. Another long journey and conversation ensues.
Nigel will stop and drop you off at Benedict Point. Afterward, he suggests you speak to his friend Irish in order to secure some weaponry for your attack on Fort Mercer. You'll find him in the livery shop in Armadillo.
