For anyone who has read Friel’s Bible or employs his workouts, I’m planning on topping up a TR Low Volume plan with his AE2 workout. Pretty simple directions; ride at your aerobic threshold HR for the duration of the workout. AeT HR estimated at 30bpm below your Lactate Threshold HR, +- 2bpm. The q…

How have you estimated your LTHR? How recently have you tested it? Either way, you’re overthinking it. The intent of Friel’s workout is long and steady in zone 2. You can do that by power, HR, or even RPE. Ask a bunch of coaches about which way to do that workout (power, HR, or RPE) and you’ll get …

Honestly I think this is wicked common and I see it every year especially starting a big base again. Your aerobic fitness is high compared to muscular fitness. That and sometimes zones don’t necessarily align perfectly.

As Landis noted, it is very common for zones to not align correctly….and I don’t agree with Friel’s calculation for AeT HR. Subtracting a defined number from a variable one will result in different HR values. IOW, training zones are defined by percentages…either of FTP or Max HR. A set number (in t…

Great advice. If I’m trying to ride as close to the aerobic threshold as possible, where does that typically land power wise?

[image] Kaj_Johnson: If I’m trying to ride as close to the aerobic threshold as possible, where does that typically land power wise? It is not possible to calculate it yet from power or by HR only (you can use DFA Alpha1 that apparently works well) It is around rpe 5/10, the point where your …

If you can figure out where your LT1 is on any given day, you’ve discovered the endurance unicorn and are destined for millions. I ride around 65% of FTP and that’s good enough. There’s really not much additional benefit to your aerobic metabolism to ride higher in zone 2, so I aim for the low or m…

Generally the way I do these workouts is negative split at or slightly below perceived LT1. Start low. I might start at 60% for the first hour, 63% then up to 65%+ over the course of the next two hours or more. I’ll watch HR and RPE throughout, and if either gets higher than I want, I’ll back it off…

If you want to open this particular can of worms: [image] Iñigo San Millán training model Training I think it’s time to start a dedicated thread on this. This is an interesting topic, the Pro/Elite is not the proper place for this. Personally, I find this an interesting mo…

[image] Kaj_Johnson: Pretty simple directions; ride at your aerobic threshold HR for the duration of the workout. AeT HR estimated at 30bpm below your Lactate Threshold HR, ± 2bpm. The question: when I ride at this HR, I am solidly in my Zone 3 power, about 80% FTP. Does this not seem too high …

This certainly sheds more light on the issue. Thank you!
