"The silver lining is I now get the whole year to really work on things and making sure I get everything right so hopefully I can set some times to reflect the hard work I am putting in.
"You don't want to be running the Commonwealth Games standards. You want to be so good that the standards are what you hit even if you are having a bad day."
But Millar may have an unlikely Commonwealth Games lifeline in the 4x400m relay team.
He is in the frame for the team after the selectors asked him to trial last month. Despite a virus and not training for weeks, Millar did a PB by half a second in clocking 46.99s to become the fourth fastest Kiwi over 400m this season.
No decision has been reached to send the team or not but Millar is hopeful.
Millar credits his training partner Codi Harman (second fastest New Zealander sprinter) as one of the reasons why he continues to improve.
"Not a lot of other people around the country train with someone with the ability to beat them on any given day. Neither Cody or me want to let the other get to the line first so because it is so competitive, we are training a lot harder without realising it.
"The better he gets the better I have to be and vice versa."
