Your comprehensive race day forecasting
You know, I JUST ran the Twin Cities Marathon, and this weather forecast is causing me to reconsider taking a break. The weather is just too perfect in Grand Rapids, and fairly close in Detroit. So here's what's happening. Detroit is going to be 33 degrees at the start. It wouldn't be a bad idea to wear tights if you have sore knees or ankles in cold weather, but after mile 2 you should be able to heat up. Temps will warm to just below 39 degrees 3 hours later, and the lower 40s closer to 5 hours in. If you're going for sub 3, this is your day. While the lower 40s are ideal, you'll have full sunshine. The only minor problem will be the wind, which will affect you on the bridge (cross) and portions of Belle Isle. Otherwise you will have a tail on most of the course. Check back on Saturday night for mile-by-mile weather.
In Grand Rapids, the weather will be mostly the same, but maybe warmer by a degree or two at the start and finish, so 35 at the start, and 43 at the finish line for those running at 3 hours. Later times will warm by a degree. You'll have light west winds at around 3 to 5 mph, so that will not be a factor until the last 3 miles, and only as a cross wind. In other words, if you're in excellent shape, this has an excellent chance of being a PR race. More to come on Saturday!

If you cannot remove the sticker, get a black pen and black out the price.
