Intended to drop power to 185W, but settled at 187W.  Tried to hold the rate at 18 for the first 20 minutes.

20′, r18, 186.9W, AvgHR: 142.9, Lactate: 1.6

No problems with those numbers.  Pushed on at 187W and was fine through the next 2 20′ pieces.  In the last piece, I kind of did a slow motion crash into the wall.  My HR started to run away from me and I felt a much higher level of fatigue.  So, after about 10 minutes of trying to hold 187, I slowed down to about 180W and essentially paddled it out.  HR stayed stubbornly high though.

Tomorrow:  Same thing, but at 185W
