My sister is racing Chicago Marathon and trying to run a PR! Try LMNT electrolytes: https://www.drinkLMNT.com/allie for a free sample pack. The World Marathon Majors are electric. It was so fun to cheer on Taylor and watch her (and thousands of others) achieve a big goal. I also got to do my first run back after a break from running, record a podcast with Runna, and stay in a penthouse! #AllieOstrander #ChicagoMarathon Oiselle apparel & MY LINE of clothing (!!): Oiselle.com Check out COROS for super accurate data.
