Forza Horizon 4

This achievement requires you to complete a 3 lap race on the longest course in the game, "The Goliath," using a Forza Edition car, which you can identify by their Pink, Purple, and Blue gradient border (the name should also contain "Forza Edition"). Forza Edition cars are typically obtained through Wheelspins, which you will earn as you play the game. If you have a lot of credits and have somehow not obtained a Forza Edition car yet, you can try looking on the Auction House for deals. There are also several houses in the game that give you Super Wheelspins when bought, which are far more likely to give you a Forza Edition car than regular Wheelspins.

While any Forza Edition car will work, I'd pick the fastest one you have and fully upgrade it so the race goes faster. For reference, I used a 2010 Pagini Zonda R upgraded with Don Joewon Song's tuning package and each lap took right around 9 minutes.

**Although most unlock this achievement without issues, it appears to be buggy for some. My best guess is that it's some sort of intermittent server/connection issue, since people have reported back that they used the exact same car and settings as I did it still didn't unlock (Thanks to Nollie37 and TEN SQUARE 3 for the info). If you've followed the instructions exactly and it didn't unlock for you, I would recommend trying a force a restart of the game and maybe waiting a little before trying again. So far everyone who reported it as not working was eventually able to unlock it.**

Getting The Goliath course

Blueprints

There are two ways to complete a 3-lap Goliath race. The easiest way by far is to use a community created blueprint which you can find in the pause menu under Creative Hub -> Blueprint Events (Big thanks to SWYD1 for pointing this out). Make sure that the race is at least 3 laps.

If you're having trouble finding a blueprint and no one you know can make one for you, you can use one that I've created. The instructions on how to do this are below.

1) Go to Creative Hub->Blueprint Events (The big blue box in the top center)
2) Hit the "View" button (left of the Xbox button) to search, and enter 104585455 under the "Share Code" option. Alternatively you can enter my gamertag "Mitch Connor" under the "Creator" option, but you will need to set the "Route Length" option to "Unlimited" for the race to appear if you do this (thanks to b0seiju for pointing this out). Leave all the other inputs at their default.
3) Select "Reaping The Rewards Short" which is a custom route that is much shorter than the full Goliath course (Thanks to Funky Monkee for confirming this works). It has no checkpoints, so just drive around the starting post.

Note: Playing a Co-op race doesn't seem to work for unlocking this achievement (Thanks Yeast for helping confirm this). The only thing that hasn't been tried yet is playing co-op when all players in the race have unlocked the Goliath themselves, however I doubt this will make a difference so try it at your own risk (if you do try this and can confirm one way or the other, let me know). Doing laps in Rivals also does not count towards this achievement. (Thanks BestAphid68996)

Unlock it yourself

The second way to get the Goliath is by unlocking it for yourself, which is much more time consuming. If you really want to do this, The Goliath unlocks when you reach Level 20 in the Road Racing Series. This will take you far longer than actually racing The Goliath itself. Completing all of the Road Races in the game should get you to around Level 10, and for the rest I recommend repeating long races with upgraded cars and Influence bonus masteries.

With the new route creator option, we are now able to make really short laps for the Goliath. I can confirm I was able to get this achievement from a very short 3 lap race.

Laps can be as quick as 15 seconds and the full race is less than a minute for 3 laps.

You're free to make your own blueprint with the route creator. I've also setup a blueprint dedicated specifically for this achievement if you would prefer.

Blueprint is named:
Easy "Reaping the Rewards"

EDIT:

"Since the blueprint creator search function does not allow a search by creator, friending Paulmolive and then looking on Friends and Followers is a very fast alternative." - S1deSh0w

Thank you for the comment S1deSh0w. You're all free to friend me if you would like to find the blueprint easier.

To first of all unlock The Goliath race, you need to reach level 20 in the Road Racing Series.

This isn't really a quick process but the best and quickest way that I've been doing it is by going to Hollyrood Park Circuit, heading to the blueprints and choose a 50 lap race.

Now it all depends on the car you have but I've been doing each race in just over an hour in an S1 Alfa Giulia. I was level 16 before I done the 50 lap races and had to do it twice to finally reach level 20.

Hope this helps.

I have created a blueprint for this achievement.

It’s 3 laps of the proper Goliath track (not my own route), and only cars you can choose are forza editions.

To unlock this achievement I have made a easy way for you, first you need to reach lvl 20 on road racing series so go to “elmsdon on sea sprint” and search “way to goliath” (jeyzy liadon creator) on custom events, if you use a forza edition with event influence boost it will be more faster.

Once you unlock the goliat go to it with your forza edition car and search for my creation “David” ( same jeyzy liadon creator) it is a really short race of 3 laps and the achievement its yours
