Bike Course: 112 miles

The Ironman Hawaii bike course is a 1 loop course, heading up the west coast of the big island to Hawi. Starting at T1 you will follow the town roads towards the Queen K, a non-technical course perfect for aerobars. Comprised of mainly rolling hills the only elevation you need to be concerned with is the 12 mile climb towards Hawi, which is also the turn around point. The ironman hawaii bike course is well paved and clearly marked. Besides the lava fields the course is known for its legendary winds, hence why disc wheels are not used.
