How to format my data to a duration displaying mm:ss

I've been looking at the documentation for some time now and i can't seem to figure it out:

I'm trying to enter my pace (in minutes per kilometer), and i've tried:

duration(a,'InputFormat','mm:ss');

where

a = {'5:45', '5:45', '4:57', '5:06'}

but it still shows me the pace in hh:mm:ss

ex:

ans = 

  1×4 duration array

   00:05:45   00:05:45   00:04:57   00:05:06   

How do I make it display as 5:45 (or 05:45)?

a = {'5:45', '5:45', '4:57', '5:06'}
a = duration(a,'InputFormat','mm:ss');
a.Format = "mm:ss"

I was just missing that last line, it works perfectly, thanks!
