- The more races have been run on that course, the more significant the ratings are. However, actual conditions on race day (e.g. waves during the swim, wind or heat) will impact the times for a race.
- The Ratings can be used to compare times from different courses. For example, an 8:37 in Barcelona (course rating of 23 minutes) is a similar performance to a 9:29 in Wales (course rating of -29 minutes). The Ratings are based on a 9-hour Ironman (consisting of a 55 minute swim, a 4:50 bike and a 3:10 run plus five minutes for T1 and T2). For finishes around 12-hours, the numbers should be increased by a third (i.e. 11:30 in Barcelona is comparable to 12:39 in Wales).
