Threshold / V02 combo 1:11:18 [3] 7.72 mi (9:14 / mi)
ahr:152 max:186
Run 3: Threshold/Vo2 combo workout. Do your normal 15:00 easy warmup and a few strides. Then run 15:00 at about 8:20 pace (ie, tempo effort). Then run 5:00 - 10:00 easy ending up at a nice hill. I’d like you to run approx 10:00 of hard uphill running; ideally 10 x 1:00, but do what you can with the terrain you have. This is the “v02” part which means you want to be huffing and puffing at the top. Jog back down the hill easy and take another full minute at the bottom of rest before the next hill sprint. Finish up with at least 10:00 easy running for recovery. As I mentioned above, adding time to cool-down is a great simulation of the feeling you’ll get later in an ultra because you are running on tired legs and with lower blood sugar. When doing a longer cool-down after a workout, I've felt much the same as I do late in a 50M race for example.

-loved this workout; didn't have access to hills today but stepped up the sprints to try and get heart rate up as much as possible
-confirming that the tempo effort was 8:10-8:20
-the 1-min sprints were between 6:00-6:30
-definitely experienced low blood sugar / tired legs and enjoyed the cool-down training :)
