Some runners think that a new pair of running shorts will bring them good luck or give them an extra boost of confidence on race day. Although they might feel good when you try them on, a new pair of running shorts might ride on you or cause chafing
once you start running. You don't want to discover at mile 5 of a half-marathon that your new running socks
are causing blisters
or your new sports bra
is not giving you the support that you need.
The racing solution: "Nothing new on race day" should become a familiar phrase to any road racer. Race day is not the time to experiment with a new pair of running shoes, running shorts, or a new sports bra. It's better to stick with your tried-and-true favorites that you know are comfortable. If you get a race T-shirt in your race goody bag before the race, you definitely don't want to wear it during the race. Not only are there bad luck superstitions associated with wearing the race T-shirt, but it will also make you look like a rookie.
