It occurs to me that my training benchmarks may not be readily apparent to most, since I'm sort of using a hodge-podge of power training, heart rate training and perceived exertion training. Basically, what I've tried to do is incorporate all of those systems into my own, which accounts for all three methods.
Basically, my scale, L1-L6 (training zones or levels) refers to the different physiological systems that are trained at each level. There is a corresponding range of power, heart rate or perceived exertion data that fits within those zones depending on my current fitness.
The system is based on Lactate Threshold, which I define in the same vein as Joe Friel as the point at which training intensity is such that lactic acid builds in the muscles at a faster rate than it can be cleared by the circulatory system. It is at this point that work being done by the muscles becomes very difficult, and breathing is fairly "labored" making it difficult to carry on a conversation. This is L4 on my scale.
| Level | Name | %FTP | %LTHR | RPE | Description |
| L1 | Active Recovery | 0-55% | 68+ | 0-2 | very low level exercise. Minimal sensation of effort or fatigue. Typically used for active recovery after strenuous training days (or races), between interval efforts, or for socializing. |
| L2 | Endurance | 56-75% | 69-83% | 2-3 | "All day" pace, or classic long slow distance (LSD) training. Sensation of leg effort/fatigue generally low, but may rise periodically to higher levels (e.g., when climbing). Breathing is more regular than at level 1, but conversation is still possible. |
| L3 | Tempo | 76-90% | 84-94% | 3-4 | Greater sensation of effort/fatigue than at L2. Breathing is deeper and more rhythmic than L2. Conversation is somewhat halting, but not as difficult as at L4. |
| L4 | Lactate Threshold | 91-105% | 95-105% | 4-5 | Just below to just above time trial (TT) effort. Continuous sensation of moderate or even greater effort. Conversation is difficult. |
| L5 | VO2 Max | 106-120% | 106% + | 6-7 | Strong to severe sensations of effort/fatigue. Completion of more than 30-40 min total training time is difficult. Conversation is not possible due to 'ragged' breathing. |
| L6 | Anaerobic Endurance | 121% + | N/A | 8+ | Short high intensity intervals designed to increase anaerobic capacity. Severe sensation of effort/fatigue. Conversation is impossible. |
*These levels are a combination of the Friel (heart rate) and Coggan (power) training zones. Typically, there is a 7th level that (Friel-Power, Coggan-Neuromuscular Power) that works on training explosive bursts of power. Since this is an Ironman plan, I won't be using L7, and will likely not venture into L5 or L6 much, either.
Glossary:
Threshold - The effort at which lactic acid accumulates in the muscles faster than it can be flushed. Muscles tire quickly at this effort.
FTP - Functional Threshold Power is a training benchmark that establishes power at threshold, or the average power you can sustain at threshold
LTHR - Lactate Threshold Heart Rate is the HR "equivalent" of FTP. This is essentially the average heart rate a person can hold while exercising at threshold intensity.
RPE - Rating of Perceived Effort is a subjective 1-10 scale that ranks your effort as you perceive it, 1 being easiest and 10 being extremely hard.
By considering FTP, LTHR and RPE during each workout, I can get a sense as to how I am performing, and how well I'm recovering from previous training stresses. For example. If my power on the bike or my HR seems low, but my RPE feels high, I may not be adequately recovered from a previous workout, and I should either stop the workout (if it's a run) or scale it back to active recovery or endurance effort (for bikes and swims).
It's a science, but one about which I've learned quite a bit since I started this training thing four years ago.
As a last bit on this entry, I'm having to try to be much more efficient with my training for this Ironman race. In 2004, I tried to do large volumes, and ended up alienating the family and probably doing more harm than good to my training plan. I was always tired and I ended up bagging a lot of workouts, so that my overall volume really wasn't that big. This year, I have promised to be more attentive to the family and to restrict workouts in a couple of ways.
First, from the day the twins are born until January 1, 2007, I have promised that no weekend training will take more than 1 hour. In addition, my entire plan must leave weeknights free. So, all training must be done in the morning and/or at lunch. Finally, as a self-imposed restriction resulting from my training plan, no long rides (3+ hours) will occur until late May, when I start ramping up to Ironman volume.
This should be interesting. Stay tuned for updates. Only 362 days to go.
