The Goliath race is the final Horizon Festival Mexico event in Forza Horizon 5. It's one of the most difficult races in the game, and the biggest by distance in the series's history — a single circuit lap runs 34 miles (55 kilometers). But before you enter the race itself, you'll need to unlock it. Here's how to do just that.
How to Unlock Goliath in Forza Horizon 5
There's no big secret to unlocking the Goliath race in Forza Horizon 5. All you need to do is complete all the races in the Horizon Festival Mexico event. Of course, this is easier said than done, and will probably take you a little bit of time, but there are no shortcuts to the Goliath. You'll simply have to grind out those races to get to the big one.
Once you've unlocked the race, you can find the starting line by following the map marker that appears to guide you to it. Beginning at the beach, this race will take you through the entire map, letting you revisit the sites of all your previous conquests along the route. It should take around 15 minutes to complete the race, and a first place finish will net you a few achievements.
