12 week Aerobic Engine Builder (Intermediate)

Hi guys, I have developed this base training plan for athletes that are quite advanced in their training and are looking at spending a 12-week period on building their base up. It focuses on 3 4-week blocks that are split up by slightly reduced training loads to allow the athlete to recover for the next bout of training. The focus for these blocks of training are around strength sessions on the bike, tempo and sweetspot work which are essential in increasing aerobic fitness as well as spending several hours on the bike in the lower cycling zones. It is not essential that you ride every single day. If you need a day off, feel free to take off a recovery day if you feel you need to. Also swapping sessions around are fine if you are busy on certain days. By the end of the plan, you should find that you are able to ride very efficiently in your endurance zone and feel comfortable riding for hours at a time. This should ultimately set you up for your build and peak phases on races that are coming up.
