Minor rule changes in Ironman triathlon races from 2017
Triathletes bound for Ironman triathlon events should be aware that there have been some minor changes to the competition rules for the 2017 season. In a nutshell, disc brakes are allowed, no more bare-chested running nor listening to music.
Here are some excerpts from according to the Ironman website.
1. Yellow card penalties will change from a stop-and-go to a one-minute stop-and-go penalty.The goal is to standardize the time that athletes cited for a yellow card rule violation spend in the penalty tent on the bike course or served on the spot while on the run course.
2. Bicycles with disc brakes are now allowed globally in all non-drafting middle and long distance triathlons, including IRONMAN and IRONMAN 70.3 events.
3. In an effort to better define the rule prohibiting bare torsos during the bike and run, and to align with the global standard, uniforms with a front zipper must not be undone below the point of the end of the breastbone (sternum). If not remedied promptly, athletes will be issued a disqualification.
4. With athlete safety in mind, we’ve amended the rule prohibiting the use of communication devices. The rule now prohibits athletes from using communication devices in any unsafe or distractive manner. We understand and appreciate how technology is evolving the sport of triathlon, however, the use of technology in any distractive manner is grounds for disqualification. For example, a “distractive manner” could include, but is not limited to, making and receiving phone calls, sending and receiving text messages, playing music, using social media, and taking photographs.
5. In addition to the above changes, and with respect to the PC Open Division, visually impaired participants may use a single guide of either gender. In this participatory division, and because of the challenging long distance nature of IRONMAN’s events, visually impaired athletes are encouraged to find a compatible guide.
