Adlington swam faster in the 400m in 2012 than she did in 2008 and was beaten by an Olympic record.
At the British Championships this year she swam slightly faster but still wouldn't have been fast enough for silver.
In the 800m she improved on her qualification time (which was the fastest time in the heats) but again two other swimmers swam faster in the final. If she had replicated her most recent form at the British Championships she would have won silver by a tiny fraction but she still would have been a way off gold.
Her best time in the 400m was set at the World Championships in 2009 (and was 'only' good enough for bronze at the time).
Her best time in the 800m was set at the World Championships in 2008 and she hasn't come close to that since then.
I wouldn't necessarily be looking at PBs, but more at recent/average form and if you look at it like that, Adlington far from under performed, she just wasn't as fast as two other people in both events.
It's nothing to be disappointed about and I preferred the swimmers attitude to the rowers who see to reflect the public mood that anything but gold is an abject failure.
It is Addlington's 800m which should come under scrutiny; that is her event. She "should" be peaking between now and the next 3 years, instead she is in a steady decline. In the 400m she has got slower relative to the pack, which she can argue is because it is not her event (but might also point to why she didnt succeed in the 800m).
I would not look at recent form- they have had 7 years to get to their best for the London Olympics, which they have not. Poor recent form is equally problematic- why are they all producing poor form just before the biggest event they will ever swim in? Something has gone wrong.
The medals or lack thereof are not the problem, it is the performance. Quite simply they are not producing their best and they don't seem to really care. I don't see how we can applaud that.
Instead of focusing on my disregard for the BRitish showing, i would prefer to talk about the swimming event as a whole, which, in this Olympics has been incredible. The mens breastroke pair were sensational, Ruta was so classy, the Chinese swimmers raised the bar and Phelps was just a phenomenon.
What Phelps did is something like winning the 200m sprint, the 110m hurdles, the 400m hurdles, the 400m and the 800m, the long jump and a triple jump. The fact that he is multi-disciplined and actually competed against the very best in that field, and won, is mind blowing.
Ennis is amazing but her multi discipline is against generalists- Phelps went out against the very best in the world at each discipline and won. Quite incredible.
