Big Crown: Showdown

This method requires a second controller! If you do not have a second controller(or boosting partner(s)), that will complicate things in terms of the consistent distance you will get per round as you may need to play online with randoms.

I’d recommend you save this achievement for last, as you will work your way through a chunk of the distance through natural play.

So to begin, from the main menu, sign in a guest account and go to:

Local > Custom Game > Create

In the playlist, select “Rooftop Run” (2nd row, 1st option, you also need to only select it once).

In match settings:

-Lives set to 7
-Victory Points set to 50
-Map Speed set to high

The rest of the settings can remain default.

Now, run through the entire map. Your second controller will be at 2 hearts (possibly 1 heart, but doesn't happen often) by the time you reach the final door. What I’d recommend is that you bring yourself down to 2 hearts as well by jumping off the map. Now, rinse and repeat this process for 25 rounds to finish the game.

General Tips

-Run circles in the starting area during the beginning countdown and zig zag around the map when you can. You don’t only have to go straight! Every little bit of distance counts!

-When you go down stairs, you run faster! So as you go up / down stairs, run right back down / up them to get a little extra distance and then make your way back as the screen is probably losing you. There are two large staircases near the end of the map that are perfect for this!

This method throughout 25 rounds can net you roughly 17% for the achievement(almost 4.5 miles), you can check your progress on this achievement through the achievement app.

ClockKing1986 has mentioned an alternative method in the comments. For those who are interested in taking their time by using a slower pace, give their comment(s) a read.

Good luck and happy achievement hunting!

I would do everything breaking bear has said except put lives to 10 and have map speed slow.

The second controller guy will have 2 lives at the end and I would kill myself at the end until I had two lives left. Thus you will have 25 rounds.

Putting the map on slow you will have more time to run around. The best spots are the two long stairs, get there quick and jump to the top and the go down and repeat until the map moves you too far.

I was getting at least 1 percent every run doing it this way. You should get at least 25% on 25 rounds maybe 1 or 2 percent more.

Building on the other solutions:

Stage: construction (dead center)
Lives 10
Victory 50
Speed Slow

This stage is wide with few jumps and obstacles. You'll spend most of your time charge punching back and forth. Make sure to punch the other player down the course once or twice at the beginning; this will ensure that they're alive long enough to give you time to use on the raft in the canal just before the end and the 30 second countdown at the finish. Beware of auto targeting, try to stay away from P2 while spamming punches. I'd get one death usually so a game would last 6 rounds, and get around 10% progress a game.
