There’s additionally a lesser-known issue: foot-strike hemolysis—the repeated affect of physique weight on the ft can break down pink blood cells, lowering iron ranges over time.

Jessica Brake realized this the laborious approach. A passionate marathoner, she had simply certified for the Boston Marathon with a private finest of three:29. However afterward, her efficiency declined sharply. Regardless of coaching simply as laborious, she completed her subsequent marathon almost an hour slower.

Years after her irritating post-Boston hunch, she got here again stronger, clocking a brand new private finest of three:29:40 on the Mississauga Marathon and ending because the twelfth total feminine.
It was the sturdy comeback she by no means anticipated.
