What are IMR and IMX? Two USA Swimming programs that reward well-rounded swimmers. IM Ready (IMR) uses five shorter-distance events; IM Xtreme (IMX) is the next step up, with five or six longer events. IMR is a stepping stone, not a prerequisite for IMX.

• Each program runs on the USA Swimming season, September 1 to August 31.
• Every required event must be swum in the same course (SCY or LCM), at official meets, and can be spread across different meets.
• Each swim earns power points for age, sex and event; the points are summed into the swimmer’s IMR or IMX score once all events are done.
• Scores and national, zone, LSC and club rankings are viewed through a USA Swimming account. Participation also counts toward Bronze, Silver and Gold Medal Club recognition.
