If you guys are using anything but weatherunderground you can’t be trusted.
apple weather? Wtf is that? They make cell phones.
Yeah, I usually use weatherunderground for my local forecast, but they didn't have a 14 day when I started this thread. Their forecast high of 65° in Boston vs. 67° in Hopkinton. There's a small chance or rain/showers in the early morning which could shift a few hours, but shouldn't impact race times, just people's comfort prerace.
gonna be warm it looks like. How drastic of an effect will this have on paces?
I think it really depends on the climate where you did the majority of your training. As someone who lives in the upper Midwest, I've always struggled in "warm" spring marathons. My body is so accustomed to cold weather. But for those that have spent at least the last month training in similar conditions I wouldn't expect much change in strategy for those people. It'll be warm, so it looks, but certainly not hot as most people would define it.

Many of the calculators have the tailwind a larger benifit than the heat a negitive. My thought is the condition are still more likely to cuase people to blow up with fluid/stomach issues and cramping. Also wondering if the tailwind is the same speed as running pace if it will feel warmer than actual.
"Your effective speed with the tailwind is your running speed (10 mph) plus the speed of the tailwind (10 mph), totaling 20 mph. So, with the tailwind, you'd effectively be running twice as fast as your actual speed."
Weather forecast looks great as of now especially if the winds hold up where they are now. This will probably be my last Boston so I really hope there's good weather.
BTW, findmymarathon puts up the Boston Marathon weather up each year. You can put in your time and wave and it will give you the weather at the start halfway and in Boston based on it. Gives how much headwinds and tailwinds too which I like.
Yep. The details matter, and Rojo's gotten them badly wrong (what a shock).
He describes the course direction as (to the) NE. This is wrong. It's a lot more east than north.
ENE is pretty accurate; NE is way off.
He also describes the predicted wind direction as (from the) NW. This is also wrong.
It's actually almost exactly WNW.
When you put those two big mistakes together, you get a radical distortion of reality.
If it was as he described it, it'd be a wind perpendicular to the course, which would be a slight net-negative.
In reality, it's looking like the wind's about 45 degrees off the runners' direction, which will give a roughly 70% tailwind vector. And at 12-13 mph, that'll be pretty significant.
And now the temps are back under 60, so altogether it's looking really good.
Gonna be *fast*. Should be fun to watch. Too bad we don't have a top-form Ryan Hall to take advantage. (Though we do have his wife, but I don't know how fit she is. It'd be awesome if she could crack 2:20 to put a cherry on top of her great career.)
Maybe this is the year CJ finally gets that 2:08 he's seemed like he might be capable of for quite a while.
lfg boys!! dew point in the 40s, low 60s ambient shouldn't impact paces much at all (and if anything, it'll be cancelled out by the tailwild). PR'S TO COME BABY
Yeah going to be the best Boston conditions in a while. Temp set for 60 basically the entire race. But low humidity = low dew point. 1st Boston in a while where you don't need to make a pace adjustment. Guessing it'll be the fastest/deepest Boston in a while down through the mass race. A northwest wind isn't a tailwind. It'll be more like a cross wind. South southwest would be the ideal Boston wind. Should help make 60 degrees feel a little cooler & should be more/less negligible on race times. Everyone is packing up anyways. Tuck in & go after whatever you trained for.
