What did I do wrong?

That is unfortunate.
I am unable to tell with these 3 photo's where the focus may be if there is a sharp focus point due to a couple of factors.
For the first shot the bike and rider are clearly not sharp but they are surrounded by asphalt which is difficult to tell the sharpest location.
The second shot has the subjects face in shadow which inherently makes it look softer.
The third I tried to see if one bike/rider was more in focus than the other. My general feel is that the lead bike may be just a tad sharper but this could also be due to the lead bike being brighter and I therefore perceive it as sharper.

My suggestion if you are to rent this lens again is to see if you can also rent the usb dock for it. This lens allows you to perform focus adjustments with the dock. Then you could test and correct any issues.

Wish I had better info.
