An unsupported Tacx dumb trainer and no power meter, hence not joining the league (would be unfair).
I didn't stop because I blew up on a climb, I could have kept pedalling but my HR spiked too high because of a surge I put in about 30 seconds prior, to carry some speed into the climb. When I get delayed HR spikes I start to feel shonky (not lactic acid) and twiddling a small gear while focusing on my breathing wasn't reducing either my HR nor the shonky feeling.
This is not representative of effort, nor is it close to my recent zwift numbers.

Now you know why I won't ride without a HRM![]()
Maybe an extended period of Zone 1,2 to get your cardiovascular system more efficient.
My brother in law is doing a months Endurance building with TR. He is using a traditional base plan. I'll try a collate his long workouts over the month. Im hoping he will see a flat-lining plot from his heart rate staying mainly in zone 2.
He is only into 2nd week so early days. Currently his HR would keep climbing to zone 5 over a low power 2hr15 workout.
