I’ve noticed that for whatever reason, it seems I’m able to push my heart rate higher riding outdoors than indoor.
As an example, I recently did a V02 max session where the intervals are 3 mins at about 120 to 115% of FTP. Heart rate topped out at around 155 and I felt like I just couldn’t get enough air. After 4 intervals I backed it down to 90-95%.
