One of the most frequently asked questions I get about what is the best protocol for carrying your custom formulas for training and on race day. Here are my thoughts after racing on my custom formula for years but also having worked with literally thousands of coaches and athletes.
Every athlete should know how to calculate their sweat rate in order to have a hydration target. The goal is to see exactly how much dehydration you incur during your workout and in turn, determine your hourly fluid replacement (how much you need to drink). When you are done with this sweat rate formula, you will have a hydration target that you can use in both training and racing.
I have been racing endurance events for a long time. Last week I was trying to remember the date of my first race, I think it was a duathlon in Columbus Ohio way back when Pyro pedals were the hot equipment. Late 80’s or early 90’s I think, I really cannot remember which. The only hard clues I have is some finisher plaques from the Muncie Endurathon dating back to 1991. So it has been a while.
Sweat Rate Testing. Most athletes this time of year find themselves measuring and analyzing things like VO2 Max, Lactic Threshold, etc. On the hydration side of this is Sweat Rate testing. Understanding the amount of fluids your body uses and loses on a per hour basis can give you a much better understanding of how many ounces of fluids you need to be replacing each of activity. Below is a great way to find what your sweat rate is.
Trying to use food + drinks + gels is a complicated proposition ESPECIALLY when I am racing. If I have to think about more than one thing, I am going to probably going to mess it up. Multiple tasks are a sure recipe for failure and possible DNF. I may have food in my pocket…but I certainly ROCKS in my head.
