This is normal, I think its intended to remind you that sprinting drains your energy.

thats not normal, i dont need 2 warnings, it allready warns you when energy is almost drained

it's normal. It also happens when you do a power jump (holding X). I think they did it to indicate that you are using energy for an ability rather than to just warn you that it is depleting.

It displays the activation of speed mode.
