This sounds awful. But looks like you did pretty well except for 1 and 7. I can imagine having your visual abitlies fluctuate during a race can be disconcerting.
Isn't this the second major problem with your contacts in the last month or so? Sounds like a poorly-fitting contact:
...In order to assure that the curve of the lens properly fits the curve of your eye, your doctor will measure the curvature of the front surface of the eye with an instrument called a keratometer, to determine the appropriate curve for your contact lenses. If you have astigmatism, the curvature of your cornea is not perfectly round and therefore a “toric” lens, which is designed specifically for an eye with astigmatism. In certain cases your eye doctor may decide to measure your cornea in greater detail with a mapping of the corneal surface called corneal topography....
Maybe you need a 'mapping?' I wore hard contacts exclusively for 35 years; never had such problems! Good luck.
I think just a case of inadequate care in getting it seated. I could feel that something wasn’t quite right. I should have taken it out and re-positioned it. I did that after the morning race and the contact was fine for the afternoon.
