A running bra, or sports bra, is a must-have for every female runner, no matter her bust size. Larger-breasted runners particularly need full support, because they experience greater breast movement during running. According to a review of sports bras in "Running Times" magazine, a good bra minimizes movement and protects "delicate and fragile" breasts against general discomfort, chafing and possible sagging over the long term. In addition to finding a bra that fits well, wicking material, flat and/or hidden seams, and a combination of breast encapsulation and compression are key features to look for when choosing a running bra.
Encapsulation and Compression
Running bras are mostly about physics: encapsulation and compression are the two ways to minimize breast movement. Encapsulation surrounds each breast individually, providing support in all directions. This can be achieved with molded cups within the bra's construction or with cup-like support from a circular system of mesh and elastic. Compression, on the other hand, pushes breasts together and against the chest cavity, "thereby reducing the amount of weight the bra has to cantilever," as reported in "Discover" magazine. Running bras that offer maximum support, especially for larger-breasted women, are those that combine encapsulation and compression.
Fabric and Seams
Technical or "breathable" fabrics--usually synthetics such as polyester, spandex and nylon--wick moisture away from the skin and dry quickly. In running bras, these fabrics not only help keep you cool as you sweat, but they can also help prevent the bra from chafing your skin. Sports bras made with cotton retain wetness, become heavy and may chafe. ConsumerSearch.com recommends also taking note of the bra's seams, which should be flat or hidden, because rough seams have a tendency to irritate the skin. Seamless running bras--they do exist--are even less likely to cause chafing.
Proper Fit
Even with supportive construction, breathable fabric and comfortable seams, a running bra is only as good as its fit. Having your measurements taken professionally can help you find the correct size and proper fit. Moreover, while a sports bra should be snug enough to minimize bouncing, it should not be so tight that it's constricting or you can't breathe normally. "Experts say you should be able to slip two fingers under the straps," reports ConsumerSearch.com.

this is a great article...except one thing: where do we find these magic bras that are seamless, wicking, and hold in those of us with large breasts? these bras are nowhere to be found. we all know what we need. we just can't find it. i'm desperate to find a bra that supports my 32DDD breasts but doesn't rub raw and cut me everywhere when I'm on my 10+ mile runs!
