Couldn't make it to the Big Island this year for the return of the Hawaii Ironman? We'll take you there with our age-group gallery.

If you want to see the full spectrum of human emotions, watch the age-group finish line at the Ironman World Championships. Elated, bewildered, and completely wrecked - these athletes felt it all, and you will, too.

Gustav Iden is making his debut at Ironman World Championships this week—we look at his unique ride, dotted with custom flourishes.

We found the brightest, blingiest, and most meaningful-looking bikes from the best long-course age-group women in the world. (And yes, there's a fat tire bike with aerobars and a basket.)

It's all about testing the warm waters of the Kailua Bay and preparing for two days of upcoming races. We take you there.

Kristian Blummenfelt's bike of choice may be unconventional, but it does the job. Pictured with his disc-wheel training setup, find detailed pics and specs on his Kona race-day rig in our gallery.

Abs, legs, luchador masks, and more than a few tushies made their triumphant return to the Big Island with this year's always-epic Underpants Run. Click, scroll, enjoy.
