Following is a series of key points detailing information about this new program:

Program Description
Swimmers will participate in a designated combination of five or six events and, based on the power points scored for each of those swims, earn a combined score that will be called the IMX Score. These combined scores will be ranked by single ages with rankings and recognition available on the USA Swimming website.

IMX Score:
Using Hy-Tek Single-Year Age Group Power Points, all USA Swimming registered athletes earn an “IMX Score” based on the cumulative point total of the combination of IMX events for their age level. The overall IMX score, as well as the swimmer’s current best score for each IMX event, appears on the athlete’s My USA Swimming Page. As times in these events improve, the swimmer’s IMX score is automatically updated.  In order to receive an IMX score, a swimmer must legally swim each IMX event for their age level in a sanctioned meet at least once during the season.

Age Groups and Events:
The following single age groups and event combinations will be tabulated and scored for both men and women:

9 & Under; 10-year olds:
200 IM, 200 Free, 100 Back, 100 Breast, 100 Fly

11-year olds; 12-year olds:
200 IM, 400/500 Free, 100 Back, 100 Breast, 100 Fly

13, 14, 15, 16, 17, and 18 -year olds:
200 IM, 400 IM, 400/500 Free, 200 Back, 200 Breast, 200 Fly

My USA Swimming Page:
We strongly encourage swimmers who have not done so to create a web account to be able to access their personal My USA Swimming Page! If a swimmer has already swum the event combo for his/her age level, the IMX score and ranking now appears in a special section of the swimmer’s My USA Swimming Page. The only place to access an overall IMX Score, as well as the swimmer’s current best score for each IMX event, is on that swimmer’s personal My USA Swimming Page. Other features of this special page include a display of personal best times and corresponding power points, a list of meets participated in, a graphical display of times info, seasonal and lifetime best comparisons, in addition other member only features.

Period:
The IM Xtreme Challenge will be tabulated annually for both the short course yard and long meter performances. Final short course rankings will be tabulated using results achieved between September 1 and May 31. Final long course rankings will be tabulated using results achieved from Sept 1 – August 31.

Hy-Tek Single-Year Age Group Power Points:
Rankings in the IMX program will be based on power points. Working in collaboration with USA Swimming, Hy-Tek has developed a power point system for each age level that allows for comparison of performances across strokes, distances and events, as well as between age groups. Please see the Power Points page on the USA-S website for more information.
