Running tempo (Treadmill) 30:00 [4] 4.6 mi (6:31 / mi)
shoes: Saucony Road
Looks like I run at 9.2 MPH or 4:03/km on the (non-metric) treadmill to keep it just in zone 4.
I'm hoping to hold 4:15 to 4:30 in the Tuscon marathon.
Our treadmill only goes up to 10MPH so it won't do for fast speed work but it's fine for tempo. Back to collecting cobwebs for it after this week.
