Run (Treadmill) 45:48  5.4 mi (8:29 / mi)
15 minute warm-up
Then started on "work" section
20 minutes at high intensity alternating between Z4 and Z5
Set treadmill alternately at 7.8 mph and 8.3 for these sections (about 1:45 at 7.8 and 1:15 at 8.3) Exact value changed a bit as I dialed it in, but those were typical speeds. The good thing about the treadmill is that it forces you to go the speed you set… no drifting down.
10 minute cool down
Actually felt good other than having to take a bathroom break 5 minutes in to the interval (Annoying, but it was really not an option.) Once I got back, it was a great run!
Also determined that the reason my new HRM strap doesn't work is that it won't pair with my watch… not that there is something wrong with the strap. It's a Suunto Dual - specifically made to work with this watch. New watch time? Santa? Actually, I think we're doing a no-gift/charity gift Christmas this year, possibly.
