You can also get rid of the hacky ping -n command by using timeout.

Here's the answer of MC ND with timeout. The 1 in the sample stands for 1 second.

:loop
for /f "tokens=2 delims=: " %%f in ('schtasks /query /tn yourTaskName /fo list ^| find "Status:"' ) do (
    if "%%f"=="Running" (
        timeout /T 1 /NOBREAK > nul
        goto loop
    )
)
