When you first start building back into the season, everything i’ve read over the past few months states to concentrate on Base/Foundation miles on your bike. These miles are basically long distances at a moderate effort. By doing these distances your body will build up its aerobic capacity, strength, endurance, drop weight, and concentrate on technique.
The aerobic zone is where the majority of your time should be spent when doing any type of endurance or distance competetions. This zone is where your body burns fats and carbohydrates for its energy. The aerobic zone is defined being between 60-85% of your maximum heartrate, different sites vary this percentage but this is a good target. The beginning of training in this zone, about 20 minutes, will burn more carbohydrates than fat, after about 20 minutes you begin to burn fat and carbohydrates equally. After you hit that 40 minute barrier the body swings to burning more fat than carbohydrates. In this way you can drop pounds which you will gladly miss on your long Livestrong Ride.
A heart rate monitor would be a good investment to help you stay within your aerobic zone during your base/foundation miles. I have a Polar 720 which is constantly keeping me inside my optimum training zones. If you dont have a heart rate monitor or dont want to get one yet, calculate your heart rate zones and use that zone in your local gym. Most gym equipment now has the ability to show you your heart rate by grasping the handles or some other similar method.
For me, I concentrate more on time than on distance during the base/foundation training. I usually target riding in my aerobic zone for 60-90 minutes per workout. This is by no means the upper limit as its always good to get in a nice long ride, but i do try to keep the time at least 60 or above before i consider it a good base session. If you reference Chris Carmichael’s training plan i discussed in a previous blog you’ll see that he advocates 90 minute base sessions in the beginning of his plans.
