Big weekend

Week 3 of build phase 1. (For those non-training geeks like myself it basically means its the last weekend of the first hard block of training before a "rest" week [lighter training week].) This means there is a "big test day" on Saturday. Wake up just like a race, eat then swim at "race pace" (when your swimming isn't "Jamie Vessey good" you just swim without stopping and hope it's race pace), go home rest for 90 minutes and eat then ride/run at race pace to see if I could hold the proper pacing along with nutrition. It is planning needed for the modified half-ironman in May, doing this for an Ironman will be a little bit longer of a day. 

This "big day" is even more important for me as a person with diabetes. I need to figure out what my body can handle for food/insulin. Honestly, if I didn't have diabetes there is no way I would wake up at 4:30am on a Saturday just to figure out what I can eat before a race. But through racing I'm learning more about my diabetes and about myself than I ever thought I would. Granted, the insulin ratio's will be a higher when rested/tapered but I will still have a good idea. 

Alright enough talking, on to the big day. 

Night before:
Had dinner with Jamie's grandpa at Karl Strauss. Ate a clean meal, just a little late. 60g rice, bolused perfectly. Grabbed Jumba Juice after to make sure all the glycogen stores were topped off, 121g with good bolus. All before 7:30pm. Blood sugar; 65 at 8:50pm. Corrected for low.

Wake Up
Slept well but woke up at 288. Planned to only bolus 7.5u for 130g breakfast but decided to give a shot with 10.5u. Shut the basal rate off for remainder of the day. All bolus from here!

Learned:
Question: How could I wake up so high when I normally never do, especially when I know all my insulin/carb ratios were dead on the money? 
Answer: The basal rate with that much food/insulin on board just isn't high enough. Taking what I've learned over the years during the holidays, when there is a lot more food/insulin in the system the basal rate HAS to be increased even when activity level is high. 


This lesson makes the entire day worth it. I've never figured this out during a race because I've just been mad at waking up high and then switching focus to the race. Never before taking the time to think about the high blood sugar. I've also always figured it was just anxiety from the race. (Now I get that carb loading "doesn't work" but it's better to have a 10% increased estimate than 1% under.) 

Before Swim
BS crashing, tested at 97. (Correction was far too much, obviously! Three units correction? What was I thinking.) Had 90g (65g coke, 25g gel) and 0.5u insulin. 

Swim
Swam straight 2,000Y. Got out, tested at 67. Had 75g right away with 0.5u. 


Rest of day:
The rest of the boluses throughout the day aren't really relevant to the race because I took a break and ate oatmeal before the bike. However, I needed very little insulin the entire day which is good to know. 

I rode up through Camp Pendleton to the power plan near Orange County and back. A flat course that allowed me to see if my pacing would work. I held a normalized power right on the money, figuring out I can hold more on race day.

The big test:
Get off the bike and run. It's been a weakness in both half-ironman's. 

I wanted to hold under 7:50 split's for 8 miles. I ended up holding 7:37 then jogged another two to keep loose before finishing the day. After biking 70 miles at race pace and holding that run I am really happy with how my training is coming along. Honestly, it did more than  "fitness" it showed my mind that I can hold pace through the hurt. Something I've never truly tested outside of a race. 

After this rest week I want to increase my bike miles a little more to average 180 miles/week to hit "critical volume" (currently between 130-140). By having that bike base it will do two things; help my run during the May race and put base in my legs for Ironman in November. 


Reflection:
Overall, I'm really happy with how the day went. Figuring out what I need to increase for an overnight basal rate was worth the entire day. The next "test" of my diabetes will be at the Olympic race in mid-April. 


I couldn't be happier with how my swimming is progressing. 2,000 yards is the longest I've ever swam straight without a wetsuit and it felt fine (besides the mental anguish of looking at the black line and clipping the guy in the lane with me twice). 

Big Test Day Volume:
Swim: 2,050 yards
Ride: 71.05 miles
Run: 10.07 miles
Insulin: 48.7 units (mainly from food domination following the exercise…)
