I’m sure this question has been asked before, but I’ve been unsuccessful with the search. Due to my busy workweek life all of my weekday runs are on the treadmill and long runs performed outdoors on the weekends. Should I compensate with an incline percentage to simulate outdoors? I’m training with a Stryd power meter and unsure if power is power between treadmill and outdoor runs.
In my opinion, Power is power. Just hit the numbers within your zones. You can see how incline and speed impact your power numbers. This is why it’s nice to have power if you live in a hilly area, because terrain ultimately doesn’t matter so long as you stick to the number
I absolutely recommend having at least a 1% incline on the treadmill to account for the lack of wind, and terrain that you will get on outdoor runs. You will feel a lot more comfortable at 1% on treadmill. Power is power as divitogca said, so using power on the treadmill and outdoors is going to really help keep the effort consistent for you.
