VELO's video: Beyond Limits: Testing sweat for Tour de France performance

From Tour de France pros to beginner cyclists, we all sweat. But we don't sweat the same - at least in terms of how much sodium we lose. What this means is that some riders need to replenish more salt than others during hard, hot rides. But how much? In this episode of Beyond Limits, Allen Lim measures the sodium concentrate of sweat in two Tour de France riders, Mike Woods and Tejay van Garderen. Allen picks their brains about how and why they take care of themselves nutritionally, and asks them to guess about how much salt they each lose. "In terms of t-shirt size, are you a Small, Medium, Large or Extra Large salty sweater?" Watch to see the methodology and results of the test, and the takeaway for the riders. ----- Beyond Limits is a new VeloNews Voices project featuring Allen Lim, PhD. From his academic work on power meters beginning in 1997 until today, Dr. Allen Lim has been obsessed with improving a cyclist’s performance, on and off the bike. The founder of Skratch Labs has coached some of the world’s best cyclists, including most all the American grand tour contenders of the past 15 years. In Beyond Limits, Dr. Lim brings you inside the sport at the highest levels, showing its secrets, its humanity and its significance for everyday riders as we seek to improve. Beyond Limits is made possible by support from Skratch Labs and CycleOps by Saris.
