How are your TR workout HR numbers? I find that with sweet spot workouts my HR is in a good spot, Antelope I was at high 140s every interval (max hr is 195ish). Then I go outside and ride at a similar rpe with some harder intervals and my hr is a good 15-20 beats higher.
Could be just a symptom of being outside, training with an incorrect ftp, or going harder outside than you do inside.
Also looks like you’re running outside and riding inside. Not sure that all aerobic fitness is created equal.
