OFFICIAL Chicago Marathon Weather Thread

Forecast looks great. I’ve run Chicago 3 times and would have killed for what’s predicted this year. Tuck in and you’ll be fine. Have a great run.

When the weather's hot and sticky there's no time for dunkin' dickie; when the frost is on the pumpkin that's the time for dickie dunkin'! - modified pithy verse for Chi 'Thon 2019

When Alberto is feeling unloved and the fall 'Thon season is upon us, it's time to tell Galen and Jordan to run through the wind, run through the rain, run through the frost, run through the pain; and please leave behind the L-carnitine and testosterone cream.

First time running this course, not too familiar with Chicago and how frequently we run through areas with large buildings.

But I love the point you're trying to make. It's not possible by the laws of physics, you know except when it is. Thanks for the info!

Ha ha. Yes, guilty as charged. Look, I hadn't had coffee yet.

But anyway, the wind is now predicted to be 19 mph WSW. If that sticks, hugging the left side going north then the right going south will hopefully keep things calm. That's my hope, anyway. The 1.5-mile portion that goes due west should be a bother, but then there'll be a nice tail wind for the same distance.

Will Trump carry IL in 2020?

Looks cold and windy - arm sleeves for Galen and Mo?

Conditions looking good for the JV squad.

Haha, I'll be good with anything less than snow. See ya'll there.

Wind or not the temps look perfect and I consider it a win compared to what we could have gotten (ie: heat and humidity, rainstorms)

Weather forecast is 97.9% full of angst and vitriol as the haters spew bad vibes at Galen. He will need minimum 8 hat changes to deflect the doping slurs that will be downpouring from spectators and other competitors. Mo's sunglasses and neon sleeves will also help keep this climate from impacting his performance as well.

I just hope it will be clear enough for someone to spot Alberto on the sidelines somewhere near Chinatown wearing one of those combo eyeglasses/nose/fake mustache disguises while he transmits coaching advice and sweet nothings into Galen's earpiece.

Here ya go. Put in wave and finishing time. Should be a fast race.

Anyone know if you could run sub 3 from wave 2?

Looks like thunderstorms and high humidity for race day

When it is cool or cold, the humidity is low even if the Relative Humidity is high. The reason is that the air holds a lot less moisture as the temperature falls. But I was seeing the Dew Point as being in the 30s, so the 'high humidity' is simply wrong.

Clear skies apart from 2 dirty grey clouds

No. 0% chance.

Also this is a running thread about weather before an American major. Cool & windy is the prediction. Tuck in and it really won't be that bad. The temp, itself, is perfect for running. It's all about getting in the mindset. There will be tons of people to run with. Tuck in and stay positive.

Nearly impossible. You'll be battling hordes of slow pace groups from mile 13 on.

Doesn’t it spread out by then?

A little, but you'll still run into a ton of traffic. I started from the front of wave 2 several years ago and it got pretty frustrating towards the later miles.

Ha ha, well done!

You can run Sub 3 if you can run sub 3.

I ran sub 3 from really far back.

Their headwind prediction is just stupid. Having run Chicago 5 times, you CANNOT have a headwind going both north and then later south. Or as it indicates at least 25% or greater headwind THE WHOLE WAY!!!

To me, these look like the best conditions in YEARS! I ran 2007 (dropped out - wisely) and 2008 (where is was 86 near the finish) and what I could've have run at peak form with cooler temps and low humidity?!?

Like some posters said, tuck in and go for it.

I predict a sub-2:20 for the women. Galen around 2:05-high but not winning.
