IM Xtreme is a program that allows USA Swimming members to track their time against swimmers all across the nation! Just by swimming a specific program of events, you can see where you rank against your teammates, your region and yes, even across the USA!

An IMR or IMX score is only established after a swimmer has swum all of the events required for their age group in a sanctioned meet since the start of the current season; both short and long course seasons start September 1 and end August 31 for IMR/IMX purposes. Additionally, a swimmer must complete all of the events in the same course (SCY or LCM) to have a score in that particular course.
