A number of manufacturers also make sports bras which are designed to accommodate the sensor strap of a heart rate monitor, to prevent you from having to have two separate straps around your chest.
Like running shoes, you need to replace your sports bras from time to time – with a lot of use they can last less than a year. Check from time to time to see if your bust is moving more than it should, or if you are beginning to get breast pain. You may also find that it begins to rub after a while.
T-shirts and shorts
You’ll need some shorts and t-shirts for running. At first you can just dig out some old summer clothes, but over time you may want to get some clothes specifically for running.
The most important lesson about buying clothes for running is to steer well clear of cotton. When cotton gets wet (from sweat, or from rain) it gets heavy, irritates the skin, does not insulate well and dries slowly.
