Ironman nutrition

I probably obsessed over nutrition more than anything else. I was extremely concerned that I not screw this up, because it can make or break your day.

How will I get at least 300 cals an hour in me when:
  • I can't eat solid food while I'm exercising. It just won't go down.
  • It must be portable and not heavy.
  • It must be quickly consumed.
  • It needed to be more than just carbs.
  • It was going to be a warm swim (water was 84 degrees), so starting well-hydrated was mandatory.

I figured I'd be out there for 16 hours and some change. 16 hours on nothing but gels = very unhappy stomach. And not enough protein would mean bonking. I've learned over the years that my body really likes protein, and needs it for anything more than 5 hours, as opposed to just straight carbs. I also know that I get really, really sick of the sweet stuff.

I've been using Hammer Nutrition's Perpetuem for about two years, so I knew that would be a component. It's a carb/protein drink and is more substantial than a straight electrolyte drink. The plain flavor doesn't taste that great but it's not sweet either, so it's worth a less-than-yummy taste simply to get a break from the constant sweetness.

Infinit makes a custom blended drink and I really wanted to try that with some protein in it, but time grew short and I didn't have time to get it and train with it. I did however, have a blend that was primarily carbs/electrolytes that I was used to, so I stuck with that.

Shakeology drinks have worked out well for me this year, simply because they're a more complete meal replacement than a simple protein drink, and my body seems to process it just fine. I've had good luck drinking them about 30 minutes before a race and before training, so figured they'd be worth a try as a meal replacement during a race.

Enduralyte capsules are a quick easy way to get some electrolytes in you without having to drink all that sickly-sweet junk.

So here's how the race day nutrition worked out.

Breakfast, 4am. Oatmeal with dried raisins, one boiled egg (I apologize to any swimmers in line around me)
Swim line, 5:30am, yogurt
Swim line, 6:30am, Shakeology.
- Sipped on an Infinit drink for entire time in line until 7am.
T1, 9:00am, Shakeology, two Enduralyte capsules
Bike, over the course of 8 hours:
- went through two front bottles' worth of Perpetuem
- around 3 bottles of Perform at aid stations
- several large bottles of cold water at aid stations (stopped and drank the entire bottle on the spot)
- four gels, approx one every two hours
- another Shakeology at special needs, around 2:30pm
- piece of banana at two of the aid stations
- two Enduralyte capsules at four different stops
T2, 5:30pm, drank Shakeology for dinner, two more Enduralyte capsules
Run, over the course of 5.5 hours:
- three pieces of banana at three separate aid stations
- gel every 3-4 miles since I was moving slowly
- Perform 3-4 times at aid stations (less than one an hour)
- Water at every aid station. Yep, all 25 of them.
- Bottle of Perpetuem at special needs, mile 14. Carried bottle with me and took about an hour to drink it all.

I really wanted to avoid the cramping/hydration issues that take so many people down, and measured my hydration by the number of pee stops. Peed at T1 and T2, twice on the bike, and three times on the run. All was well.

Around miles 50-60 of the bike I had cramps in my side, but remembered the advice from Coach Patrick of Endurance Nation: when your stomach cramps, drink water to dilute all the other junk. It helps settle the gut. And it worked. Before long the cramps subsided. Ditto on the run - when the stomach got queasy I would drink some water and feel better. I know the constant influx of calories/water is why I felt so good all day. I heard someone puking behind me on the run and was happy not to be them.

...and it took a couple of days to be able to eat normal-sized portions of solid food again!
