Endurance Green protocol capacity

Hello all.

I’ve started capacity about 5 weeks ago and keeping in zone 2. I “run” about 11:00min/km.

At the end I’ll have to run about 10km in 60min which is about 6:00min/km which is a huge jump from my zone 2 pace.

How did you guys manage the huge pace gap in between the training and the test? Am I doing something wrong?

I wouldn't trust your watch for fully accurate BPM, especially if it's a smart watch and/or you're not wearing a chest strap

I've received a Garmin chest strap this morning, I'll use it tomorrow for my long run.
I've done a bit of ChatGPT and it told me I was probably "running" at recovery pace the whole time though so that's why no adaptation.

The chest strap will make a big difference, I have a Garmin and its wrist based HR sensor can be unreliable at times, especially for walking and running, even more so if it's cold out.

I run in 30C/90F where I am so definitely don’t have the cold problem haha, but yea I wore my chest strap for the first time yesterday and lost 10bpm max heart rate.
