The goal behind his training program is to provide a challenge to each runner regardless of their ability or experience by using a variety of training paces and intensities. By challenging users in this way means specific types of endurance can be built up not only with the aerobic system, but in upper and lower anaerobic thresholds as well.

A good training program should not only provide the appropriate stimulus to the heart and lungs but to the muscular system as well. The aim with these training programs is to improve the athletes cardiovascular fitness while also improving their running economy. As the weeks go by each runner should feel an improvement in maintaining their specific goal race pace and by the time they reach the race date they will be full of confidence to go after their goals.


The B.A.A Half Marathon plan has seven levels beginning at level one for beginners and level seven for advanced athletes. Included in each 12 week training plan are half marathon specific workouts that will help you to get to the starting line with assurance.

Levels 1 - 3:
5 day per week training plans designed for the runner with a time goal of 2:00 – 2:20 for the half-marathon.  It is a great program for the first time half marathon runner or for those looking for a new twist on their normal training program and those wanting to drop their personal best.

Levels 4 & 5:
6 day per week training plans designed for the runner with a time goal of 1:40 – 1:50 for the half-marathon. This program includes one anaerobic threshold interval session, one aerobic tempo run workout plus a long run each week. This plan is for the runner that has a good level of experience in running and has ran road races in the past.

Levels 6 & 7:
7 day per week training plans designed for the runner with a time goal of 1:20 - 1:30 for the half-marathon. This program contains the full array of workouts designed to maximize performance and help you reach a new personal best in the half-marathon. Each training zone from the Blue on to the Red will increase in duration over the course of the 3 month training program. The purpose of this plan is to bring in specific endurance within each energy system that will ultimately lead to the key specific half-marathon workouts.

B.A.A. Moment 2

1935 John A. Kelley

Born in West Medford, Massachusetts as one of ten children, Kelley ran track and cross-country at Arlington High School in Massachusetts. He did not finish his first Boston Marathon in 1928, but eventually competed in a record 61 Boston Marathons. A legend of the marathon, Kelley won the 1935 and 1945 runnings of the Boston Marathon. He finished in second place at Boston a record seven times. Between 1934 to 1950, he finished in the top five 15 times at Boston, consistently running in the 2:30s. He ran his last full marathon at Boston in 1992 at the age of 84, his 61st start and 58th finish there.
