Sub X Running

Sub X is designed to help you achieve & celebrate your accomplishments as a RUNNER - the lifestyle, the community, and the pursuit & attainment of YOUR goals! We believe that whether you are striving for a Sub 5 hour marathon or a Sub 4 minute mile, you are on your own personal journey to see if you can exceed the limits you thought possible. Just like you, we have big goals - for what Sub X will be able to do for the running community - and we're excited to start sharing details shortly. So join us, and tell us....What's your X?
