About Alex

Alex started running at sixteen to de-stress and is still running today, on both road and trail: trail running and half marathons, with five halves completed. Alex has spent three years working behind the counter of a running store.

The What… Won't Tell You series grew out of that: what you see every day in a running store, and what the evidence says. Straight-talking guides, no filler, with sources cited at the end of every book.

The books are not medical texts and do not replace the advice of a doctor, physical therapist, coach, or sports dietitian.
