Good day Cristian – doing week 13 to 16 of your initial program during the period between both races is a good idea.
However, since you will have already unloaded a month before, don’t feel the need to “taper” as much before the 2nd event.
Your major objective during that short block should be to build into the intensity, all the while completing the prescribed volume.
It’s also important to keep in mind, that your “frame” will recover quicker that your “engine” post race, so be extra patient before doing anything long and strenuous. And simply focus on frequency and speed variations.
All the best!
