Premium Content Subscriber only Organisers of the iconic Byron Bay Triathlon have warned the future of their race could be in threat as increasing visitor levels derail their upcoming event plans. On April 9, Race Director Mike Crawley issued a statement to let triathletes know traffic from tourists and a population increase had resulted in a date change from Saturday, May 8 to Sunday, May 9 for the eventâs 25th year. Mr Crawley said the race change was suggested to event organisers by Byron Shire Council and the Byron Bay police. âThe biggest problem is when we close the coastal road network for the cycle course from the Surf Club south to Suffolk Park locking in tourists, visitors and locals at lunch time,â he said.
