One of the movement events, calcRunSpeed is used when calculating when the player is running, but not swimming or flying.

The movement event flow is described below:

--- @param e calcRunSpeedEventData
local function calcRunSpeedCallback(e)
event.register(tes3.event.calcRunSpeed, calcRunSpeedCallback)


An event can be claimed by setting e.claim to true, or by returning false from the callback. Claiming the event prevents any lower priority callbacks from being called.
