    It's much easier to perform it with Super Sonic after collecting all emeralds, but you can do it without him. And it's not that hard.
    I made a speedrun of this stage where you can see most of the shortcuts, good luck for this!

    Angelr1pperI didn't get the achievement when I got 1 minute and some milliseconds. Strange that milliseconds cancels the achievement. Oh well, I got it the next run anyway.

    Here's the route I too. Hopefully it gives you the tips you need to shave the seconds.

    I did this straight from the game menu without unlocking any of the Tails helps to show it can be done.
