It was very mixed. The JRs race and the C4's were in pouring rain on mostly wet grass. The next couple of races (including mine) were in lots of slick mud and no rain with it moving to sunshine. The last few races were less slick mud moving back to some mud and damp grass in mostly clouds.
As for me, I finished DFL in the 45+B's before zerogravity showed up to take pics of me in my nongreatness.
