Boston Marathon 2023
Mile 25 - Kenmore Square
My Race Fuel Plan
I am breathing hard, my quads are burning, but I am not cramping! I don’t want to walk, but I am also not looking at pace because I am giving my best effort and I am almost there, praise God!
Every athlete, and every nutrition client I work with has to figure out their nutrition or fueling plan by trial (and some errors) in the months before their race. I have tried lots of products through this training cycle and I decided to use Maurten gels. They had worked well on long runs and if I dropped 1, there were more on course.
Took a Maurten gel at Mile 0, 4, 8, and 12 but by Mile 16 my gut was in angry revolt. I stopped at a porta potty to take care of business and decided to rest my gut until Mile 17. Took a Transend gel at miles 17 and 21, as I know this pure dextrose gel will work quickly to bring the energy and alertness I needed without disturbing my gut! At the last Maurten table on course, I grabbed a caffeinated gel and ran with it in my hand for a mile or two before I got it down. At this point in the race, I don’t want anything, but I didn’t want to fade while running down Boylston to the finish line!
My fueling goal was 240 grams of carbs evenly consumed over 4 hours. I was able to consume 220 grams but most of that was in the first 16 miles, from a combo of Gatorade Endurance taken at every aid station and my Maurten gel 100’s. This is the most I have ever consumed in a race. Is it possible that this was too much for my gut? Yes, and I will need to experiment with the type and timing of carb sources before my next race!
As a registered dietitian nutritionist, I am a science nerd! I am always trying and testing new products on myself and reading the research behind these products. I then help my clients interpret and apply the research in their own lives and find the nutrition strategies that best match their goals.
This is what I do. Let me know if I can help you too!davis.rd
