Yesterday went pretty well. 2:20h (indoors) + 4h outdoors. Endurance day with some low cadence work and lowish tempo work. And hopefully the effect was greater than the sum of its parts.
What still puzzles me is the question on withholding carbs between the two sessions. Necessary?
However, I will continue with carb restriction for reasons of specificity. My races are longer, 4 to 11 hours, and always include intensity in the first part. You burn through your glycogen stores right in the beginning. To be competitive fatigue resistance is key and this means being fast while being low on glycogen. That’s why I intend to keep doing it “low style”. And hope to get some additional benefits by extending the period of elevated PCG-1a expression.
Just for context setting, this is quite interesting, as well. One of the original studies on this topic.
