On the skate times:
Yeah it sucks, but luckily the athletes were given tons of notice so they can make the necessary arrangements to condition their bodies to the competition schedule.
In practice, these guys are running longs at 8 in the morning anyway so they are used to giving a hard effort not long after dawn. The part they have to learn over the years is trying to compete well at 9-10 pm for most comps because that's NEVER when they are training or at full energy.
Not sure about other nationals but we in Canada had some senior events start at 10 am and it looks like everyone survived in tact.
Also, in singles especially the top 2 groups are skating after noon so it's not really all that bad.
I personally feel the worst part of the schedule is skating individual events on back to back days. That's the most dramatic change that was necessary to squeeze in the team event. More than any event, you are so amped up competing at the Olympics; there's no way you sleep the night after the short. It's a quick turnaround to rest, recover and practice your long (like at 6 am or whenver they get ice time) to bring even more energy for the next day.
This is why I think the men's event will again like Sochi be a battle of attrition. With the big content planned, I'm not predicting many cleanish skates. Those who do are superhuman in my mind.
