Use a frozen Metroid or a Rinka from the left to extend the length of the runway. Luring a Rinka is easiest with Morph - While morphed, barely move the bottom Rinka spawner on camera in order to have it shoot at a usable angle. Without Morph, use the top Rinka spawner and jump just before the Rinka starts moving to get a usable angle.

Requires:

{
  "or": [
    "h_canTrickyFrozenEnemyRunway",
    {
      "and": [
        "h_canFrozenEnemyRunway",

          "not": "f_KilledMetroidRoom1"
        },
        "canRiskPermanentLossOfAccess"
      ]
    }
  ]
}

Exit condition:

  "leaveWithRunway": {
    "length": 4,
    "openEnd": 1
