Extremely low blood pressure after a ride?
Last Saturday, I did a 50 mile ride at a pretty hard pace for a fat boy while doing some last minute training for my first Metric Century this weekend. When I got home I felt like total crap. After a shower, I checked my blood pressure and it was 87/44. Exactly what happened to me? Is this a bonk? I mean I could have kept going longer but for the mo0st part I was getting to be "toast". Is there anything I should have done different? I had a Clif Bar about halfway through the 3 hour ride and I drank a total of 24 ounces Gatoraid, 20 ounces Diet COke and 24 ounces water on the ride.
