IM Xtreme(IMX) is a program designed to motivate swimmers by allowing them to compare their times to those of other athletes in their age group across the United States. By swimming a specific set of events at least once per season, a swimmer can receive an IMR/IMX score based on power points, a system developed by USA Swimming.. This is a great way for swimmers to track their progress and compete on a national level.
IM Ready is a program similar to IM Xtreme that is designed for younger swimmers. If you find 200 yards to be a challenging distance, you can start building your skills by swimming shorter distances and tracking your progress with IM Ready. This is a great way to improve your endurance and prepare for longer races.
The first pharse of the IMX Challenge is called IM Ready( or IMR) and involves swimming a series of five events at shorter distances. Scores are calculated for both male and female swimmers in the following single age groups and event combinations:
The second phase of the IMX Challenge is called IM Xtreme (or IMX) and consists of swimming a series of five or six events at longer distances. Scores are calculated for both male and female swimmers in the following single age groups and event combinations:
All times MUST be achieved in one season and in one course (SCY or LCM)! Both the short course and long course seasons run from September 1 to August 31 for IMR/IMX purposes.
