Super interesting! Congrats! Would you share your hr bpm ranges for z1 and z2? I wanna compare with mine

z1 roughly 120, and z2 roughly 140. about 10 bpm lower for cycling!

Interesting. From lab my aerobic threshold is about 140 (z2), and 135ish when checking rer/fat-carb switch. When i run easy i keep it 125-135. But now im curious what even lower would do. Im not so lucky i can jog under 120 as z1, then i would have to walk-jog-walk-jog. I guess you simply are at a much higher level, so for me i still need to stay with the biomechanically sound jog which is around 142-ish. Thoughts?

Congrats on the sub 3 done the hard way, a lot left in the tank if you do more specific work, and that's evident by the drop off after 30k wh oh was always going to happen with lack of long runs in training. Well done, great effort 🙏

Thanks for the write-up and congrats on the sub 3 marathon! A lot of interesting findings especially that you were already doing a 20-22 min 5k on very little weekly running mileage.

Yes - and I think that's quite important to keep in mind. I think I do have some natural ability for running. I played a lot of soccer growing up, and won my school's cross-country most years just off of that soccer training. My best 5km as a teenager was 17:57. So even though I did relatively little activity during my 20s (<10km of running a week, and about 5-10k steps a today), I still must have retained some "memory" for how to move well. I don't think I'm an "elite" responder to training, but I certainly respond "very well" to both endurance and strength.
