determined VO2max values of these runners may have been different, equally performing runners were assigned equal aerobic profiles. Daniels labeled these "pseudoVO2max" or "effective VO2max" values as VDOT values. According to Daniels, VDOT is a shortened form of V̇O2max, properly stated as "V-dot-O2max".
With the result of a recent competition, a runner can find his or her VDOT value and determine an "equivalent performance" at a different race distance. Given that runners with identical VO2max values may have differences in running economy/efficiency, biomechanics

Training philosophy
Daniels divides running performance into six components. Daniels argues that each of these components requires a specific training intensity to improve.

of the runner's movements.
Training intensities
Daniels uses five specific training intensities to improve the different components above. A runner can determine the correct speed for each intensity based on the VDOT from a recent performance.
Easy / Long (E/L) pace
At 60-79% of maximum heart rate
Heart rate (or pulse rate) is the frequency of the heartbeat measured by the number of contractions (beats) of the heart per minute (bpm). The heart rate can vary according to the body's physical needs, including the need to absorb oxygen and excr ...
(HRmax), this non-straining intensity is used for recovery runs, warm-up, cool-down and long runs. The primary purpose is to build a base for more intense workouts by strengthening the heart
The heart is a muscular organ in most animals. This organ pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide t ...
and increasing the muscles' ability to use oxygen, and to recover between hard workouts. Daniels recommends that most training miles are performed in E pace.
Typical E runs include continuous runs up to about an hour.
Marathon (M) pace
At 80-85% HRmax, this intensity is primarily aimed towards runners training for the marathon
The marathon is a long-distance foot race with a distance of , usually run as a road race, but the distance can be covered on trail routes. The marathon can be completed by running or with a run/walk strategy. There are also wheelchair div ...
. The pace is one at which the runner hopes to compete. The pace can be included in other programs for a more intense workout, especially if the runner feels fresh and there is enough time to recover afterwards.
M-runs are performed as continuous runs up to about two hours, or as long interval training
Interval training is a type of training exercise that involves a series of high-intensity workouts interspersed with rest or relief periods. The high-intensity periods are typically at or close to anaerobic exercise, while the recovery periods inv ...
.
Threshold (T) pace
At 82-88% HRmax, this intensity is aimed to raise the lactate threshold. The runner should be able to sustain this pace for up to 60 minutes during racing. Daniels describes this intensity as "comfortably hard". In elite runners, the pace matches the half marathon
A half marathon is a road running event of —half the distance of a marathon. It is common for a half marathon event to be held concurrently with a marathon or a 5K race, using almost the same course with a late start, an early finish or shortcu ...
one, while less trained runners will run at around 10k pace. Daniels points out the importance of keeping the given pace to reap the benefits of the training.
T runs are typically performed as continuous "tempo" runs for 20 minutes or more, or as "cruise" interval training
Interval training is a type of training exercise that involves a series of high-intensity workouts interspersed with rest or relief periods. The high-intensity periods are typically at or close to anaerobic exercise, while the recovery periods inv ...
with 3 to 10 long bouts of about 3 to 15 minutes each, having 20%-25% rest intervals in between. "T" runs of longer than 20 minutes can be done at slightly reduced pace, according to a table in his book. No more than 10% of the weekly miles should be run at T pace.
Interval (I) pace
Intensity at 97-100% HRmax. This intensity stresses the VO2max to raise the maximum oxygen uptake capacity. Since the pace is very intense, it can only be sustained for up to 12 minutes during racing. To cope with the intensity, and to train for longer periods of time, this training is performed as interval training

, hence the name. The interval between each work bout should be a little less than the time of the work bout. Optimum intervals are 3–5 minutes long. There is no benefit to exceeding 5 minutes at this pace, under Daniels' theory, which means that despite the popularity of mile-repeats in many running groups, Daniels discourages them for people whose pace is slower than about 5:00/mile, preferring shorter intervals such as 1200 meters.
For example, an I session can be 6 x 800 m at I pace with 400 m recovery jogs. At most 8% of the weekly training miles should be I pace.
Repetition (R) pace
R pace is very fast training aimed to improve speed and running economy. The training is performed as short interval training, with typically 200 m, 300 m, or 400 m work outs, with full recovery intervals in between. No more than 5% of the weekly miles should be R pace.

Critique
Tim Noakes has proposed that maximal exercise performance is regulated by a " central governor" rather than a limiting cardiorespiratory function (i.e. VO2 max
VO2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. The name is derived from three abbreviations: "V̇" for volume (the dot ap ...
). Noakes challenges the explanatory power of Daniels' training model (Cardiovascular/Anaerobic) stating that there is a lack of published evidence supporting the claim that each training intensity only improves one of the six physiological components described above. He also states that Daniels' division in components is also not considered complete, e.g. leaving out the muscles' ability to absorb the pounding of running a marathon. But he has acknowledged the efficacy of Daniels' training methods, and stated that science may one day catch up with the explanations, but his methods are effective.
