I would say quite the opposite. Ackley knows what he is up against now and also knows that the 1600m can be his to win (3rd in 2021, 2nd in 2022). He'll go for the 1600m and won't lose to Gabelman again [prediction].
It will be great to see them race again with their different styles: the front runner vs. the patient kicker.
What will be interesting to see will be if Ackley does go for the double in Columbus in June. He was set up for it last year but in the end DNSed the 3200m.
