This is my personal modification to the FIRST approach of adding a fixed number of seconds per mile to marathon pace. I believe that adding 15 seconds/mile to a 6:00 pace is a much greater difference than adding it to a 10:00 pace. The figures below add a percentage of the MP to the time. The percentage is calculated so that it the average across the main VDOT values (30-85) is the same as the FIRST values. This gives slower runners a larger offset from MP than faster runners. | This is my personal modification to the FIRST approach of adding a fixed number of seconds per mile to marathon pace.

1 Introduction
Your VDOT is , which is a measure of your running performance. Below are training paces for the Jack Daniels Running Formula and FIRST training programs, as well a race time predictions.
2 Jack Daniel's Training Pace
These training paces are used in Jack Daniels Running Formula. I have included the purpose that Jack Daniels stated, along with his duration advice though I do not necessarily agree.
3 FIRST Training Pace
These training paces are used in FIRST, (Furman Institute of Running and Scientific Training) programs. These paces are calculated, so may differ by a second or so from the published tables
3.1 FIRST Tempo and Interval Training
3.2 FIRST Long Run
Paces for long runs based on the FIRST approach of using Marathon Pace (MP) plus a fixed number of seconds per mile.
3.3 Fellrnr's Modified FIRST Long Run
This is my personal modification to the FIRST approach of adding a fixed number of seconds per mile to marathon pace. I believe that adding 15 seconds/mile to a 6:00 pace is a much greater difference than adding it to a 10:00 pace. The figures below add a percentage of the MP to the time. The percentage is calculated so that it the average across the main VDOT values (30-85) is the same as the FIRST values. This gives slower runners a larger offset from MP than faster runners.
3.4 Long Run Difficulty
The table below shows the percentage of Glycogen used on runs of different length and pace. This is one way of evaluating the relative difficulty of different longer runs. The table makes use of a number of assumptions, as listed below, but I believe this is still a useful way of evaluating training runs.
- The calculation assumes that the marathon distance at marathon pace uses are hundred percent of available Glycogen. However the percentages can also be looked at as a percentage of the difficulty of the marathon race.
- The research article by Romijn in 1993 provides the calculation for relative Glycogen use a different intensity exercise. (For those interested, the formula used is y = 0.0021x2 + 0.7896x - 21.031, where X is the percentage of V̇O2max and Y is the relative percent of Glycogen used.)
- 100% of V̇O2max (vV̇O2max) is assumed to be .
- The energy cost of running a given distance is assumed to be constant, allowing the percentage of V̇O2max to be determined by running speed.
- The calculator assumes that the rate of glycogen consumption remains constant for a given pace.
- Remember that All models are wrong.
3.4.1 Difficulty with Absolute Offsets
Many marathon training plans use an absolute offset from marathon pace for their long runs, such as "marathon pace plus 60 seconds/mile". The table below uses this approach, even though it has the flaw that a fixed offset is proportionally larger for faster paces. For instance, 60 seconds per mile is a much greater reduction in pace for someone with a marathon pace of 6:00 min/mile than someone running 10:00 min/mile.
3.4.2 Difficulty with Relative Offsets
The table below uses a similar approach, but uses a percentage of the target pace rather than an absolute offset.
4 Predicted Race Paces from VDOT with Heat Index Adjustment
The predictions for 40f are the baseline values, with adjustments for higher temperatures. The Impact of Heat on Marathon Performance is based on research for faster marathon runners. These predictions are most appropriate for someone running a three hour marathon. In addition, these figures are a statistical average, so individual performance can be significantly different.
5 Weight Adjusted Race Times
Adjustments based on changing body weight assumes that the change occurs only from body fat, which may not be the case. See Weight Loss and Performance for more details.
6 Altitude Adjustment
This table shows how altitude can impact running performance. The same scaling factor is used for all distances and the calculation assumes you are well acclimated to the altitude.
7 Jack Daniels Marathon Plans
These tables are included because the definitions in the book are a little complex, and it is not obvious what the total distance, time or difficulty is for of some of these long runs. This is especially true of the elite plan for non-elite runners, where there is scaling of the time & distance. These workouts are not intended to replace the Jack Daniels book, but to supplement it.
8 Jack Daniels Marathon Plan A
9 Jack Daniels Marathon Scaled Elite Plan
As the name suggests, the Jack Daniels Elite Plan is intended for elite marathon runners with a race time of 2:10 or less (VDOT 77+). The plan calls for scaling the workouts for sub-elite runners, with each mile being replaced with a time at the given pace. So an elite runner’s 8 miles at easy pace becomes 48 minutes at easy pace. Likewise, marathon and tempo paces are scaled to 5 minutes and 4:45 respectively.
10 Jack Daniels Marathon Unscaled Elite Plan
This version of the elite plan is without the scaling, and is not what Jack Daniels recommends. It is included here for comparison.
