Many endurance athletes have turned to wearables to monitor their sleep and recovery. In this episode we take a look at this growing trend with Dr Kevin Sprouse to find whether — and how — regular racers can use these devices to recover smarter and faster. We also take on a great listener question in our LFAQ segment: "What 5 things do you wish you had known the first time you raced the LT100MTB?" We think first-time (and second-time, and third-time, and tenth-time) racers will find a lot of good hard-earned wisdom in our answers.
