While she fell to 4th place last year at the Ironman 70.3 Worlds, she fully recovered a month later with a second win at the Ironman World Championship in a women’s race record time of 8:46:46. This year Ryf won her second Challenge Roth in 8:40:03, won Ironman South Africa in 8:47:02, and took two 70.3 titles in Rapperswil and Dubai.

Hauschildt is one of the most decorated Ironman 70.3 competitors in history with World Championship wins in 2011 and 2013 and a 2nd place last year. However, in her Kona debut last year, she was hit by a major version of symptoms that had been dogging her for two years. “It started off as usual with the feeling of a belt around my left thigh with someone gradually tightening the buckle until the quad was completely suffocating. I lost strength in the left leg and then when I kept pushing through the fatigue and pain, the VMO (medial side of the quad) started to tighten up like a deep cramp that was gonna tear the muscle if I didn't stop. I've had this before though, for two years now, but gradually getting worse.” Finally she had to pull out of the run at Kona. A post-race exam showed she had kinking with her iliac artery. Two surgeries later, she was on a long road to recovery. This year she decided to give her leg a competitive test but a distant 9th place at the ITU Long Distance Worlds a few weeks ago showed she was far from her standard and a competitive appearance at Chattanooga is doubtful.
“In this section detailing Melissa Hauschildt’s serious iliac injury included in the Ironman 70.3 World Championship preview, I originally misread her blog entry to mistakenly conclude that a “post-race exam showed that she had 'external iliac artery endofibrosis.’
“In fact, Melissa Hauschildt went further in her blog post to explain that that preliminary diagnosis was incorrect. Husband Jared Hauschildt wrote that Melissa’s ultimate and correct diagnosis “involved the common iliac artery (a larger artery that branches directly off the descending aorta) and more importantly it was kinking, not endofibritic, which refers to the clogging of the artery over time.” I regret the error and corrected it. - Timothy Carlson
