I am a junior road cyclist (racer) from the Netherlands. I am 184cm and around 61kg. I am very curious what your thoughts are regarding fuelling for the work requiered. My weekly training program consists of around 15 hours of training on the bike and at least once a week in the gym. I am frequently keeping track of my calories because I find it interesting and want to learn more about nutrition and what it does to my body. When I keep track of my calories and macros I eat whatever calorie needs I have on that day (2090cal base metabolic rate plus the calories I burn (usually around 1000 to 3000cal)). On bigger days I am eating around 60 to 70 percent of my calories from carbohydrates and try to aim for 20 percent coming from protein. On rest days I aim for a bigger percentage of my calories coming from protein and lower my carbohydrates intake.
