Microbursts Try #2
March 10th, 2010So I learned my lesson last week not to ’simplify’ things by doing 30 on 30 off. The workout is 15sec on, 15sec off for a reason. Ok, I get it. There are just so many on parts in 10 minutes – 20! I have a hard time with a lot of efforts. Tuesday, however, I managed to keep it together and did the two sets of 10 minutes.
Once again though, I didn’t really follow the directions. I did them too hard, and I suffered. 150% of my current threshold of about 350 would make for 525. There were 40 ‘on’ periods in the 20 minutes of painful microbursts, and I think all but a couple were over 600. I kinda knew that while I was doing the work, but I couldn’t help myself once I got going. It was hard, I suffered badly, but I liked the big numbers. 600+ is pretty cool to look at. Is that weird? I need something like that to keep me going in moments of intense agony – case in point.
It was kinda funny doing the intervals on the levee. I’d catch people, then it would look like I attacked them, only to stop, heaving for breath 15 seconds later. They’d get close, then I’d ‘attack’ them again for 15 seconds. My final interval stopped in all of its slobbery, ugly-faced glory right in front of some unsuspecting walker. If she thought bike riders were weird before…
Anyhow, the results of the fun:
SRM #1:
Duration: 9:47
Work: 208 kJ
TSS: 18.5 (intensity factor 1.065)
Norm Power: 352
VI: 0.99
Distance: 6.561 km
Min Max Avg
Power: 0 758 354 watts
Cadence: 29 109 85 rpm
Speed: 29.2 49 40.2 kph
Pace 1:13 2:03 1:29 min/km
Temperature: 18 19 19.0 Celsius
I’m still moderately disappointed that the Normalized Power is so low on these. I know, I know, I get it, but still, I figure if I spend about 5 minutes over 600 watts in a 10 minute period, the NP should be through the roof! Alas, it’s not to be. Oh well, I tell you what though – my body’s NP says that wasn’t 350 watts. I’ll ride 350 watts for an hour no problem, but you won’t catch me dead doing microbursts for an hour. I’ll die.
SRM #2:
Duration: 9:50
Work: 218 kJ
TSS: 19.8 (intensity factor 1.1)
Norm Power: 363

Temperature: 18 20 18.5 Celsius
I went harder on the second one. It tickled. I started each off with a 5-7 second ’sprint’ of sorts to get me up to wattage and speed, then I’d sit down and pound out the last few seconds whilst trying to recover before I even stopped to get ready for the next one, which was always way too soon in coming.
The workout was supposed to finish up with 10 sprints, but I only managed 6. I was completely done in after #6. To describe my ride home as a limp is giving me too much credit.
Entire workout (213 watts):

Wednesday’s workout is 4×15 at 300ish. It was easy last week, so I hope it stays the same this week.
