Notes
Uh oh. Was running 'strides' fairly easily at an alleged 23km/h (4:12/mile). Nope.
On further investigation I think the treadmill now tops out at about 16 km/h. Explains relative ease of recent 5K pace workouts. Goddamnit. I'm not going back and changing them all in the log... but I guess I'm limited to tempo pace and below from now on.
