I am a 6' 7" 240 lb rider and I have been doing a lot of reading on Hammer Nutrition's website about how much nutrition to take in each hour. I am preparing for Ride Across Indiana (160 miles) in July and want to nail down my nutrition for the event.
I estimate that the ride will take me about 9 hours including rest stop time.
According to Hammer, the following substances have the below absorption rates
Loss vs. Assimilation
What can your body really handle?
SUBSTANCE RATE LOSS/hr______________ASSIMILATION RATE
Fluids (ml) 1000-3000 (30-90 oz)________500-830 (17-28 oz)
Sodium (mg) 2000____________________ 500-700
Calories 700-900 _____________________240-280
Below are the corresponding replenishment values that we have observed for the averagesize endurance athlete (160-165 lbs/72.5-75 kg) who is fit and acclimatized (+/-5%):
SUBSTANCE IDEAL REPLENISHMENT
Fuels (Calories) 30-40%
My question is....Does my 240 lb body absorb more fluid/sodium/calories than the "average" 160 lb endurance athlete? I know I burn more calories, go through more fluid, and I assume I go through more sodium than the "average" endurance athlete.
