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.
