Clothing To Wear
It is so important
that you train in the exact outfit you plan to wear for marathon race day. Obviously you don’t need to wear it all the time (that would get mighty stinky fast), but I would recommend that it’s the clothing you wear for your long run each week. Start this process early on in training so that if you find something isn’t working (uh, hello chafing) you can change it. Once you’ve found the outfit that works for you and is the most comfortable, stick with that.
