Part 1. The "Half Full Tri" Bike Split: Heart rate and elevation data. The dehydration curve.

Howard County, Maryland is not a flat place.  A 56 mile time trial (ok, it was part of a tri) through the area was hilly.  Posted here is the heart rate and elevation profile.  Garmin data indicate about 4000 ft of up-down, up-down, up-down. (click on the graph, it is massive)


The temps were cool enough, however if you examine the heart rate you will see a general decline in heart rate over the 2 hour and 41 minute effort.  This is a mistake on my part for several reasons.
  1. Better hydration the days before was needed.
  2. Better hydration during the effort was also needed.
  3. A negative split, or at least a steady effort, is what I wanted.
Lessons have been learned.
