I wore my heart strap to bed to see how low my HR gets while I sleep and recorded it on my garmin.

Over 7 hours of sleep:

.33 miles
Average speed of 0.0
Max Speed of 0.6
Calories 0
Ascent 594
Descent 603
Max HR 89
Average HR 60
Min HR 52

Head unit was on the night stand, so no, I didn't motor for 1/3 mile. Was interesting to see the HR spikes, usually about 10 minutes apart. Min HR is too high, I need to work on that. Intervals are supposed to be good for that.
