Here you can see a typical recovery ride, one that could follow a 100-160km ride, or 3-5 hours saddle time at medium to high intensity. This ride was completed a day after an intense 5hr ride, and is 1hr30min in length.
The target wattage, in red, should be in zone 2. I'll define the watts for zone 2 to be between 55 and 75% of your Critical Power at 60minutes. For the majority of the time you will stay in this range.
While also staying within zone 2 for heart rate (dark blue). Heart rate zones are similar to Power Zones. I'll use the word "Threshold" to mean your average heart rate during the last 30 minutes of a 60 minute all out effort. HR Zone 2 is between 65 and 82% of Threshold.
In the graph, HR zones don't show up, the wattage Z2 is shown in the purple. You can see that this ride was in the middle to high end of the wattage zone 2. Power was slowly increased through the ride to illicit a heart rate response. Around 1hr10min a combination of cardiac drift and an increase in power caused too much of an increase in heart rate. Thus you see that power was reduced slowly, allowing heart rate to go back into zone 2. Toward the end of the ride a small increase in effort caused heart rate to skyrocket up, implying the ride should be ending soon.
Analysis such as these take skill, attention to detail and full grasps of the concepts. You too can get this kind of level of detail in a recovery ride, using my coaching services. I outline the zones to each of my athletes and teach them how best approach the training regimen I have planned for them.
*Note to self: make a post about cause and affect of cardiac drift.
