Can anyone give me advice on how to pace a 24 hour MTB marathon using a power meter and garmin, based on the following stats?
FTP 275 watts
Aerobic threshold power 220 watts (HR 140 bpm)
At Aerobic threshold, my Respiratory Exchange Ratio (RER) is 0.8
Vo2 max 61.8, for what it’s worth.
Course: 12km laps repeated for 24 hours. The course is on the side of a hill, therefore long steady climb to the top followed by undulating tech single track and fire road working back to the bottom.
Starting point for this - assume I know nothing!
I’m not even sure if I should be using the average power of normalised power field on my Garmin?!
Any help in deciding a pacing strategy very much appreciated!
