Your comprehensive race day forecasting
Before I get into the cool to mild rainy Boston forecast (spoiler alert!) I want to talk about something that should concern all of you. The head of Accuweather is going to head up NOAA, and there are plans to make you, the taxpayer, potentially have to pay twice to access the weather forecast; once through siphoning your tax dollars, and again by having to receive forecasts by accessing Accuweather. If you don't like this, call your representative, and you know, vote in 2020. Okay, onto the forecast! The models have shifted in a predictably unpredictable fashion, but most are in agreement that Marathon Monday looks like it will have average to below-average temperatures, with scattered rainshowers. If you're looking at historical precedents, this is shaping up to be more along the lines of 2015 instead of last year, which was awful. Think mid-40s and wind from the west to northwest for a little push until you get into Boston, where there will be a very ever-so slight headwind coming off the ocean. Either way, hypothermia is a possibility so do what I did in 2015 - wrap up in a space blanket under your singlet, as opposed to 2018 when I wore 3 layers and they were all soaked by mile 5. In other words, less is more in these temperatures. This includes socks of course. Consider wool or something that wicks away moister (never cotton), and while garbage bags are great to get you to the start, you'll heat up too much after a mile. Remember that the course actually heads east and northeast, so while a west wind will feel like a push in some cases, it may feel like a cross in others. Also, tailwinds will be felt more at the crest of each hill as most runners behind you will block. Temps in Hopkinton will be 39 to 41 at the start for each wave, you'll hit around 44 degrees by the time you reach the Newton hills, with temps reaching about 45 for wave 1, and 49 to 50 for subsequent waves. Winds will be steady at around 10 mph from the west, with slight gusts. Remember to get out of your wet clothing as soon as possible after the race, and while you might feel cool, you need to drink on the course. Good luck! I will update this as we get closer if the forecast changes!

Field mind community short. School price or power dream put eight. Identify play several.
