I thought it would be interesting to compare the 15 minutes of last Sunday's webster crit with the 15 minutes from my last Tuesday night crit.
Here's from the race Sunday:
New Range #1: Duration: 15:10 Work: 175 kJ TSS: 25 (intensity factor 0.994) Norm Power: 249 Distance: 5.725 mi Min Max Avg Power: 0 839 193 watts Heart Rate: 95 217 163 bpm Cadence: 41 124 88 rpm Speed: 2.5 32.9 22.6 mph Torque: 0 355 59 lb-in
And here's from last Tuesday:
Selection: Duration: 35:32 Work: 433 kJ TSS: 62 (intensity factor 1.023) Norm Power: 256 Distance: 15.214 mi Min Max Avg Power: 0 796 203 watts Heart Rate: 114 203 168 bpm Cadence: 40 135 91 rpm Speed: 2.4 35.4 25.7 mph Torque: 0 366 57 lb-in
It does appear that I worked a bit harder on Tuesday night. This would agree with how I felt after Sunday when I had to drop out due to the confliguration in a crash. Which was that I really felt like I had a lot left.
These don't compare
Your post said you were comparing two 15 minute segments but the last Tuesday one is 35 1/2 minutes. You did a lot more in this piece of Tuesday's race than you did on Sunday but the 15 minutes on Sunday could have come from an easier portion of the race like if you were sitting in.
