Great shes mentioning it. There is always a few during the Olympics with a lyme story too.
From last fall:
https://www.ironman.com/triathlon/news/articles/2018/10/checking-in-with-angela-naeth.aspx[ She first realized something wasn't right at the end of last season when, after her typical two weeks of rest, she felt no better.
"I kept getting extreme pain in my torso, hips and legs that would subside, but then come back," she says. "I was not recovering well from workouts and I was willing myself to get out of bed most days. I couldn't sleep, I had high anxiety, and depression was starting to set in." ]

Boy does that sound familiar (as a "has been" lol). It is amazing how some endurance athletes can endure in the roughest health and conditions when doing there "thing". Thats how strong the drive is, even when one can barely function on a "non-event" day. Driven desire, adrenaline and endorphins is an unstoppable combination with some individuals, but you pay the next few days, with lyme its "weeks" and accumulated injuries.
As a solo athlete (no team support), she most likely(?) didn't have any better sports therapy/ PT than the average Jane or Joe, wonder what she did in that area other than word of mouth.(?)
