For the geek in me. Does any one know the elevation for the Big Kahuna bike portion? The website doesn’t mention it. I figure it’s around 2k as a guess.
Thanks,
Mark

More like total elevation 539 feet. The above chart shows the out-n-back loop. So technically the ascent = descent exactly–but due to slight variations in the mapping technology, it comes out with a 6-ft difference.
Pretty flat to slow-rolling hills.

The total climbing should be accurate.

I get 416ft of climb from MapMyRun, following the highway exactly:

I did it 4 years ago but really can’t remember it. It was my first half IM and I wasn’t properly trained, so it seemed really difficult.
It is very scenic though. If it’s 400ft, I’m not complaining. ![]()
