Thanks to LMNT for sponsoring this video! Head to https://DrinkLMNT.com/FLO  to get your free sample pack with any purchase. Sean Lee started running at 45 and has since accomplished what most athletes half his age only dream of: 17 marathons with a 2:54 PR, 2 Ironmans, and 25 ultras including UTMB, Badwater 135, and AC 100. We dive into his decade-long journey, exploring lessons from early mistakes, refined race strategies, and how he balances running with strength training to become stronger, happier, and healthier.
