I attempted San Joaquin +3 yesterday, and had to stop about 30 minutes into the effort because of extreme light-headedness. The ride started off okay, with the workout feeling as tough as any other TR workout. But as it went on, I was feeling worse and worse and could feel my heart hammering away. I persisted through this - after all, TR isn’t supposed to be easy
When the valley @ 32 mins finally came, I thought it’d be enough time for my heart to calm down. Suddenly, a wave of light-headedness hit me and I could feel my heart pounding, despite being it being around 150 bpm. I had to pop off the bike and lie down on the couch for a little while.
Has anyone else had a similar experience with the anaerobic efforts? Should I mention this to my doctor?
I’m more of a steady state rider, and am new to these anaerobic/VO2 max efforts apart from those in the TR plans. A few other facts:
- I did Ansel Adams -2 last week, and excelled at it (bumping up the intensity up each set, with the final one at 143%)
- I’ve failed a few of the general build workouts before, due to muscle fatigue rather than feeling light headed
- I ate my brekkie roughly 45 minutes before my ride, and had some ride snacks between my efforts
I wonder if the light-headedness has happened because I’m not used to these type of efforts, and would love to hear your thoughts.
