Plan was to do 10x3-min intervals with target HR of 178 and recovery jog of either 1 minute or until HR dropped to 130, whichever was later. Unfortunately, it took forever for my heart to recover to that level, so the recovery jogs took far longer than expected and I ran out of time and had to cut my workout short. I did the workout at Sugarhouse Park.
2-mile warmup around outer loop
1: AHR 165/MHR 177 (5:21/mi)
Recovery jog of 6:21 (are you kidding?)
2: AHR 169/MHR 181 (5:26/mi)
Recovery jog of 5:56
3: AHR 172/MHR 179 (5:17/mi)
Recovery jog of 5:38
4: AHR 171/MHR 181 (5:39/mi)
Recovery jog of 2:34 (no idea why it got so much shorter)
5: AHR 171/MHR 181 (5:45/mi)
Don't know how long recovery jog took--had to restart workout on Garmin
6: AHR 173/MHR 180 (5:44/mi)
Recovery jog of 2:18
7: AHR 174/182
Recovery jog of 4:20 and HR was still around 140
I don't know what to make of this workout. I think the faster intervals, in addition to being at the beginning of my workout, included only 1 of the Sugarhouse hills, while the slower ones included both, which may explain the wide variation in pace. I have no idea why it was taking my heart so much longer to recover during the early intervals (and again after number 7) than on 4-6. I should note that the Garmin does not display HR when in interval mode (I forgot to set a target HR when I programmed the workout), so I was guessing except on the recovery portion, where it displayed how far above my target I was. It seemed like I was able to get down to around 140 bpm within a reasonable amount of time, but the drop from 140 to 130 took a long time. Maybe it would make sense to make 140 the threshold for starting the next interval. Finally, I was tired after the workout but not nearly as tired as I would have expected. Since I only did 7 repeats and not 10 and since I had tons of recovery in the early part of the set, that was not surprising.
