Download the profile save here[drive.google.com] and follow the steps below:

1. Unlink your 2K account if you have set it up. Otherwise, start with the next step.

2. Go to your documents and find the folder "My Games".

3. Navigate to Artemis/Saved.

4. Here you will find the folder "SaveGames". Back it up and replace it with the one you downloaded.

When you relink your 2K account later it should offer you to download your original save but I'm not sure so just create a manual backup to be safe.

Optional:
In case you would like to space out both achievements you can use this profile first[drive.google.com] to only unlock 3K Drive and then do 6K some time later.

Boot up the game and drive around for a bit. The remaining distance to reach 6000 miles on this profile is around 600 meters so you should be able to get there in no time.

After a minute or so of driving you'll unlock the 6K achievement and if you are missing the 3K one you will unlock that as well.

There might be additional achievements that will pop but you likely already have them. Still, I felt that it was worth mentioning.

Big thanks to rlyehG for providing me with the profile.

I initially had this guide as part of a bonus to my other one but I messed up the files and lost the save that I prepared when it was still at just under 6k miles. Thankfully, this one is working as intended so it gives anybody who wants it the option to skip the ridiculous grind.

And if there is something wrong with the download links, let me know.
