Don't know if anyone else has seen this but the bike course is going to be 170km not 180km. It's a tough course I rode the full two loops twice as training for Chattanooga, but i do Ironman to challenge my self and I signed up knowing how tough this course will be. Just wondering why you shorten a course 10km and call it and Ironman. I was fine with Chattanooga being long but shortening a course makes no sense at all it's an endurance challenge.
Here's the link to the new distance
