Jack Daniels is one introduced the concept of top picksspecifying training paces based on fitness, and measuring fitness based on race performance, something other plans, including [[FIRST]] have built on. Jack Daniels The book provides a series of plans for various distances, various abilities and ways of calculating the correct pace for each workout. The book is well written, and Jack Daniels is one of the most respected coaches; Runner's World famously called him "The world's best running coach". However, the plans require some hard work to interpret and analyze, as they can involve multiple segments at different paces. This article should be read in conjunction with my [[A Comparison of Marathon Training Plans| Comparison of Marathon Training Plans]]. {{BuyAmazonSpecificProduct|AZID=1450431836|AZN=Jack Daniels' Running Formula}}
=VDOT and the Formula =
The 'formula' in the title of the book refers to the calculation of the various training paces that he used. The book includes tables to calculate "[[VDOT]]", which is a measure of fitness and running ability. The term comes from [[VO2max|V̇O<sub>2</sub>max]] which is a measure of aerobic capacity, and if you look closely you'll notice that the 'V̇' actually has a small dot above it, hence 'V dot' or 'VDOT'. Typically the value for VDOT is a looked up from a race performance, and the resulting value is usually fairly close to the runners actual [[VO2max|V̇O<sub>2</sub>max]].
* '''E'''asy. The E pace is for easy running. It is typically used for recovery between intervals, the bulk of many long runs, and "non-quality workouts". In the third edition, this is a range of paces rather than a single specific pace.
* '''M'''arathon. This is a runners predicted or actual marathon pace, and is used as a component of a number of marathon training runs.
* '''T'''hreshold. Sometimes referred to as [[Tempo paceRuns]], this is intended to be around the lactate threshold[[Lactate Threshold]]. In the second edition, there is a table (7.1) that provides modifications to the T pace for longer tempo runs, but this has been dropped in the 3<sup>rd</sup> edition.(Science indicates [[Tempo Runs]] should be avoided in favor of other training paces.)
* '''H'''ard. The third edition introduced the idea of hard running that is based on subjective effort rather than a specified pace.
* Interval'''I'''nterval. This is the primary pace used for intervals, and is intended to maximize [[VO2max|V̇O<sub>2</sub>max]] by running at the pace that corresponds with [[VO2max|V̇O<sub>2</sub>max]]. (This is known as 'velocity at [[VO2max|V̇O<sub>2</sub>max]]', or simply '[[vVO2max|vV̇O<sub>2</sub>max]]'.) You can read more about this at [[Aerobic Interval Training 101]].
* '''R'''epetition. This pace is a higher intensity than the I pace and is anaerobic, but is generally longer and slower than true [[High Intensity Interval Training]].
==Half Marathon Plan==
The half marathon plan has recommendations for a buildup phase of general running, followed by workouts for 18 weeks in three further phases. Phase 2 has three quality workouts; long, R intervals, and a combined Tempo/R interval session. Phase 3 also has three quality workouts; long, I or H intervals, and the combined Tempo/R interval session. In phase 3 the two interval workouts are on back to back days, making it tougher. Phase 4 has two quality sessions; a long run and tempo intervals.
==Fitness Plans==
There are four plans designed for general fitness rather than racing, each 16 weeks long. There is a white plan for learning to run using a run/walk approach, then a red intermediate plan, blue advanced plan and gold elite plan. Each of the red/blue/gold adds increasing levels of difficulty and interval training. The plans are also structured so that you can progress through white-red-blue-gold, building your fitness as you go.
=Third Edition Changes=
The third edition of the book includes numerous changes.
* The table of race performance to [[VDOT]] has not changed at all, but there is now a table for those with slower performances. This covers VDOT values of 20 to 30, mile race times of 9:10 to 12:55 and marathon times of 4:57 to 6:44. However, I don't believe the book provides adequate plans for these slower times as only the novice plan include a run/walk approach.* The Easy pace is now a range of paces roughly centered on the second edition's single Easy pace. The range is 76 seconds/mile wide for VDOT of 30 down to 42 seconds for a VDOT of 85. The second edition used about 74% of [[VO2max|V̇O<sub>2</sub>max]], and the third edition uses 70% to 79%.
* Paces for T, I, and R have not changed, nor obviously has the M pace.
* There is now the idea of '''H'''ard running which is based on subjective feel rather than a specified pace.
* There is no longer a table for longer Tempo runsand the T pace is now only used for interval training.
* An approach to measuring overall training stress has been added, assigning points to various paces. This approach is similar to [[TRIMP]], but would require far more effort to track and calculate without some type of software.
* Where the second edition directed half marathon runners to use either a marathon plan (if they were slow or fast), or a 10K plan (if they were faster), the third edition actually includes a half marathon specific training plan. This plan is 24 weeks long and includes easy, tempo, hard, marathon, long, and repetition training.
* The marathon training plans have been expanded; see above for details.
** The novice plan is somewhat similar to the second edition but the specific workouts have changed.
** The 2Q plan resembles Plan A from the second edition, but there are now seven different plans depending on your weekly mileage. There are plans for up to 40 miles/week, 41-55, 56-70, 71-85, 86-100, 101-120, and over 120 miles/week. Some workouts are based on time rather than distance, so the details will vary with both weekly mileage and fitness level.
** The 12 week plan is actually the last 12 weeks of the elite plan in the second edition.
** There is a new plan called the 4-week cycle that is a 26 week plan and is somewhat similar to the old Plan A but every fourth week has no quality workouts.
** There are two sets of plans that are more rough outlines than fully specified plans. The five weeks plan gives five weeks that can be repeated and there are three 18 week programs; two by distance and one by time.{{:Comparison of marathon training plans-suitability}}[[Category:Training]][[Category:Marathon]]
