The epic scale of the author's journey (accomplishments included, although she is less than concerned with those) is impressive; no doubt about it. The first half or so of the book felt, at times, oddly uninspired and yet intriguing, owing to her unexpected and wide-ranging experiences, which mostly seem to predict her 'endurance as a lifestyle' life, but are shared with a tinge of detachment and (painfully honest) lack of direction. That's not inherently/entirely a bad thing. I think Lizzy was just being forthright about not often knowing the "why" (of running and various life choices). The final third of the book gets very emotional and philosophical, by comparison. The thread woven throughout, if there is one, is a sense of not answering a/the question, because maybe she/we can't know the answer, and/or it's fluid and different for everyone, even if there are some universal truths hidden within our journeys. She sort of leans into that, comfortably, which is probably uncomfortable for most readers, as would similarly be the case in life. All in all, rather than remaining frustrated by all of this, I ended up appreciating her perspective and intention in writing this. Sure, it could do with another thorough round of editing, but if you can look beyond the technical imperfections/quirks (including some unnecessary repetition and confusion/awkwardness in who she's addressing at times), there is a unique/beautiful story and message here. I'd give 3.5 stars if I could, but am happy to round up in this case.
