You will need to dress in layers. It will be 41F at 7:00 am, and 51F by 10:00 am. The general rule of thumb is "if you are warm when you start running, you are probably overdressed. This does not mean "be cold", but be careful not to over do it. If you are so layered up that you sweat a lot, this will make your clothing wet, and then make you cold.
Because of the cooler temps, I picked a route that go away from our normal roads. You will go past the hospital, and have a pretty good hill to climb. You also will not hit water until mile seven, so be prepared if you need to carry. I did only pick one route. You all know the roads well enough now to add on as needed. I did not have a 20-miler that went past the hospital, but I really wanted to mix up the routes some.
This really is a great "dress rehearsal" day for your marathon or half-marathon. Think about what you plan to eat on race day. What do you plan to run in? What socks and shoes will you use? Are you going to race in a cotton throw-away shirt? The more you make tomorrow like race day, the more prepared you will be.
Once again, I need to start early because soccer games. If anyone can put out fluids, it would be a big help. That way I can run from home. Drinking fluids is still critical even though it is colder. With so many people going 20 miles, it is very important that we not run out of fluids. Please comment below.
