" When I eventually figured out my food intolerances and a better relationship with fueling, I brought [my marathon PR] down to 2:44 within a little under a year."

Jenny Grimshaw, VP of marketing at EQUIP*, and now a 2:36 marathoner, joins us on the Lane 9 podcast. Jenny is also a mom of 2, and navigating prophylactic surgeries to reduce her risk of breast and ovarian cancers (with the BRCA-1 gene). Her postpartum running experiences have been full of PRs, as she has figured out her own fueling needs, how to balance her identity as a runner with all the other things she does, and has worked with a coach to better balance her training volume and find her confidence as a runner. 

Jenny shares:

  • her early experiences with food intolerances and GI distress that were assumed by physicians to be anorexia, but would later be more correctly classified as ARFID
  • the anxiety and panic attacks that she dealt with as a young runner, and injuries that plagued her through college, related to fueling, mental health, and wanting to explore life outside of running
  • why she got into longer distances after her collegiate T&F years
  • the gastroenterologist appointment that changed everything for her
  • how she brought her marathon PR from a 3:13 to a 2:36 (not to say "you can, too!" but to give just one example of how fueling and mental health impact our experiences in sport)
  • why she was drawn to EQUIP, and her role there

*EQUIP is a virtual eating disorder treatment company that offers care in all 50 states. They're also part of the Lane 9 Directory.
