I did the Darwin workout this morning and had this new and quite unpleasant experience during the last interval.
first three intervals went fine, hard but manageable as expected for this type of workout. But two minutes into the fourth one, it seemed like hell on earth, I was actually shaking on the bike, arms, shoulders and neck were shivering and shaking uncontrollably towards the end and my heart rate went way up (+20 from previous intervals at the end). I finished on will power and I was fine shortly after the end of the hard effort
My question: did I just run out of fuel? Did Patrick Swayze’s Ghost visit me? have any of you had this type of experience, and if so, what did you attribute it to?
here is a link to it.
Thank you for any comments
(additional information: I have pushed myself very hard before, during races and group rides, crit races with 188 heart rate average, rides with 1.2 IF etc) but this came out of the blue with no warning on any of the three previous intervals that all felt pretty much the same. )
