UPDATE IN IRONMAN
The age-group draft zone for all Ironman events has been increased from 10 to 12 metres, with pass time increased from 20 to 25 seconds. (Professional draft zone remains at 12 metres). Lengthening the zone will make the bike leg more of an “individual effort”, and enable referees to spot flouters, say organisers. Athletes can now wear elbowlength sleeves on non-wetsuit swims. And only blue-card rule violations (drafting and littering) will count towards the “three strikes and you’re out” disqualification.
