Breaking Up Your Move

You can break up your move, using some of its movement before and after any action, Bonus Action, or Reaction you take on the same turn. For example, if you have a Speed of 30 feet, you could go 10 feet, take an action, and then go 20 feet.
Moving between Attacks. If you move on your turn and have a feature, such as Extra Attack, that gives you more than one attack as part of the Attack action, you can use some or all of that movement to move between those attacks.
Using different speeds. If you have more than one speed, choose which one to use when you move; you can switch between the speeds during your move. Whenever you switch, subtract the distance already moved from the new speed. The result determines how much farther you can move. If the result is 0 or less, you can't use the new speed during the current move. For example, if you have a Speed of 30 and a Fly Speed of 40, you could fly 10 feet, walk 10 feet, and leap into the air to fly 20 feet more.
