Base training

The racing season is over, the nights are drawing in and it isn’t raining as much as it did in the summer. It’s time to do a lot of base training. This means hundreds and thousands of kilometres over the next few months. The aim of the base training is to become much more efficient at fat metabolism; in other words, to be able to give as much power as possible using fat as the energy source. I will be doing low-intensity rides and measuring how much my power output increases.
The ultimate aim of this is to be able to use as much fat as possible during a race. At any moment, I have enough energy in fat for at least 20,000 km of easy riding. During a race to sustain the needed power output, the body uses sugar as main type of energy source. The problem is that even if I fully load my glucose stores (liver and muscles), it will only last for about 30 km. So, if I become more efficient at using fat, I will be able to give full power at 40 km time trial.
