Some modifications directly affect career dynamics; others simply reinforce or clarify existing criteria.
The big change: 20-meter drafting for professionals
The most relevant modification is the increase in the drafting zone in the professional category, which goes from 12 to 20 meters, measured from the front wheel. The maximum time to complete an overtaking maneuver remains at 45 seconds for the PROs.
For the age groups, the distance remains 12 meters y 25 seconds to complete the overtaking between age groups. However, the regulations now specify in more detail how they should behave when interacting with the professional race.
An age group triathlete cannot position themselves directly behind a professional or "cut in" between two legally spaced PROs.
If a rider catches up to the professional group, they must maintain a 12-meter distance from the last rider or overtake within the established time limits. This adjustment is designed to protect the PRO race without compromising the fairness of the age group.
Top tube: clear limit of 10 centimeters
Here there is a real regulatory change. Any element attached to the horizontal tube of the bicycle may not exceed 10 centimeters tall from the top edge of the tube and must not cover the steering area. Furthermore, the athlete will not be allowed to rest their body on that element.
The sanction foreseen is disqualification. This measure seeks to align with international standards and limit extreme aerodynamic configurations that had begun to appear in long-distance tests.
Use of cameras and devices: more forceful wording

If a triathlete wears the front zipper open or their shoulders bare, they will first receive warning and opportunity to correctA time penalty will only be applied if you fail to do so. It is an adjustment in the practical application, not in the technical requirement.
For Open Division: denomination adjustment
