Spawn a Zeb, stand at the edge of the crumbles, and spin jump to the right a moment after it begins moving toward Samus; turn left just before landing, then do a delayed damage boost to make it under the first gate. Face left again, quickly lose i-frames using either X-Ray or a blue suit, then damage boost again to get under the second gate.

Both boosts must be performed on the last two frames of knockback, to ensure Samus is high enough to reach the gate. For the first boost, jump can be held the entire time. For the second boost, unless X-Ray is available, there is not much time to set up a buffered jump input, so it may be easier to aim to press jump and right simultaneously after being hit.

Use the respawning Zeb to set up with reserves and enough energy to tank one Small Sidehopper hit without triggering Reserves then perform a 'slow short-charge' across the speedway: you must hold run at least until you have enough speed to get under the shutters. 1-tap shinecharge is used to shinecharge over the Small Sidehopper Pit, before passing the 2nd to last shutter. Fall in, take a hit for i-frames so you can land and be ready to wind up before you get hit again. Once you have blue suit you can simply Morph and roll through the bomb blocks to escape.
