854. Jenny Grimshaw, 2:32 Marathoner

"I had this sense of nostalgia, of we're going to look back on this as something special. We all felt a little bit of something magical going on."

She's come a long way, baby! Jenny Grimshaw returns to the Ali on the Run Show, this time as a 2:32 marathoner. Jenny just ran four-minute personal best at the California International Marathon, qualifying for the 2028 Olympic Marathon Trials with room to spare. This is the same Jenny who spent years trying to break three hours. The Jenny with a long history of race anxiety. The Jenny who dropped out of CIM in 2022. In this episode, Jenny, a mom to two young kids who lives in San Francisco and works full-time, talks about how she made that 2:32:50 happen, and how she has kept chipping away at her marathon time and enjoying herself along the way. Jenny also has the BRCA1 gene: She had a preventative prophylactic double mastectomy a few years ago, and will have her ovaries removed next year.
