All About IMX / IMR

Sherry Mueller

“USA Swimming’s IM Xtreme Challenge (or IMX) is a national program that encourages all-around athlete development".   

IM Xtreme (IMX) is a program that allows USA Swimming members to track their times (or coaches to track their team's times) against swimmers all across the nation! Just by swimming a specific program of events, a swimmer can see where they rank against their teammates, their region, and yes, even across the USA!

IM Ready (IMR) is the little brother of IM Xtreme, tailored toward our younger swimmers. Does 200 yards seem a little much? Then start getting "IM Ready" by swimming shorter distances, and keeping track of your improvements.

About IMR and IMX Scores

Rankings in the program are based on power points, a system developed by USA Swimming.  An IMR or IMX score is only established after a swimmer has swum all of the events required for their age (not 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.

Participation in the IMR and IMX is easy. USA Swimming automatically scores and calculates results for all athlete members!

To see their scores, swimmers only need to sign up for a Deck Pass Account, then compete in each required event, at a sanctioned meet, at least once in a season. Swimmers have the option of printing certificates that displays their scores for either IMR or IMX. They can also optionally print their national, zone, LSC and/or club rankings for IMX.

IM eXreme (IMX)

The IMX ranking includes a series of five or six events at longer distances. Once you've completed the IMX program, you can find out where your IMX score ranks nationally, within your zone, within your LSC rank and on your club.

The events to qualify for an IM eXtreme score are:

10 & Under: 200 Free, 100 Back, 100 Breast, 100 Fly, 200 IM
11-12: 400 Free (LC) or 500 Free (SC), 100 Back, 100 Breast, 100 Fly, 200 IM
