Race starts in 12 hours so we want to get the thread up now in case we forget in the middle of the morning. Let's hope it lives up to the hype.
If you haven't read our previews, do so now.
Update at 8:10 pm ET:
As we've learned in recent weeks, it's critical for proper coverage to have "boots on the ground." I've emailed Prof Sean Hartnett - who is Berlin - tonight and asked him for his thoughts as he's viewed a the Marathon Professor and seen a ton of marathon WRs.
When asked about the weather he said, "Light rain now should taper off by race time, but the big remaining concern is the expected 54 or 55Â° dewpoint. Good weather but not perfect."
I asked him how the weather compares to a normal Berlin wind and dewpoint.
He wrote, "The normal dew point is 40 to 46, anything above 50 get sticky.
"Wind does tend to be 5 to 10 miles an hour so that is close to normal. We usually talk about everything needing to be perfect, perfect weather perfect pacing and perfect performance, dew points of 52 to 55 or a little less than perfect, but the extra drink stations may help a bit. "
So there you have it. It sounds like they've added aid stations which is interesting. Also in terms of splits, he won't have his own website this year as they are working with tv. Splits should be great as he wrote, "This year we have a biker on the course dropping an arm when the split marks are crossed that also sends the splits to TV. So the TV splits should be accurate and we can send you a complete list after the race."
