It feels as if my body does not deal with drastic changes very well. Where these changes result in insomnia. More recently, aggressive carb loads. I actually thought my preparation for the Sydney Marathon was spot on. Until, looking back I do remember not being able to sleep very well on the Friday and Saturday evenings ahead of the Sunday race day. I had put it down to nerves, the flight and disruption to regular programming.
So when a colleague who was preparing for HYROX mentioned that he finds that his Heart Rate Variability (HRV) is negatively impacted I paid little attention. But coming into my second marathon preparation, where the prescription is 10-12 grams of carbohydrates per kilo of body weight for three days out of race day. I once again find myself consuming 700-840 grams of carbohydrates per day and once again, my body does not deal with the additional insulin required to process the carbs. Given that on average I eat 100-200 grams of carbs a day, jacking this up 4x means the body is constantly producing insulin. Which based on a quick search on the internet, could result in temporary hyperinsulinemia which translates to poor sleep quality, insomnia and frequent waking.
Desperate for a good night's sleep ahead of Sunday's race.
