  Don’t know the answer to this unfortunately. But it will not be too far as a sprint takes too much energy. Probably 400m is the extreme – also matters how fast they’re running.

  yes it depends on your definition of sprinting. If i remember correctly, even top 100m sprinters slow down over 100m. so there can not even maintain maximum spped over this distance. But then again compared to me, a matharon runner is sprinting and they can go for hours.
