Equivalent exercise strength for hiking?

Equivalent exercise strength for hiking??

   I have been talking about heart rate base pacing during hiking.   Based on daily training data, we might be able to set a limitation of the heart rate during the hiking.  I think it works once we identify a good number.  Today, I just check the other way which is checking the heart rate number such as overall average and the maximum during a hiking and looking for a similar exercise from my daily training.

 Heart rate during hiking

   As a reference data, I pick Mt. Whitney hiking this year.  Based on my past analysis the first day to Trail Camp would be a hard section during this hiking because of weight for the backpack.  The first day overall average is 143 (bpm) and the average is 160 (bpm).  It takes about 5 hours.  This data includes rest.  So that I just focused on one section from this hiking which is about 1 hour out of 5 hours.   Then the average is 146 (bpm) and the maximum is 154(bpm) in the section.  Then I looked for a similar training from my training log.   One which is close to the section was a jogging for 90 minutes.  The average is 146 (bpm) and the maximum is 156 (bpm).   The heart rate plot is the following.

Heart rate during 90 minutes build up (running)

   If we look into detail, the profile of the heart rate is very different.  Since the heart rate during the hiking is vary.  The strength could be a bit higher than the running case and the heart rate could be increasing due to the strength and I needed to slow down to keep the heart rate lower than the target.  For the running case, it was a build-up and I slowly increasing the pace during the training.  Therefore, overall strength is probably lower than the hiking and the maximum strength would be the end of the training.  The other example is an interval training, which is 2 minutes high intensity and 5 minutes resting for 3 sets. For this training, after the interval section had completed, I did about 10 minutes running with a medium pace. The total training duration is just for 30 minutes.  The average heart rate is 145 (bpm) and the maximum is 161 (bpm).  This is probably closer situation as the hiking.

 Heart rate during interval (running)

   Based on this comparison, the equivalent training for the hiking is something similar as a training for runners.  90 minutes build-up / an interval is a sort of point training for runners.  To build a reasonable fitness level for the hiking, people need to do such training in regular basis.  Or people might need to slow down during the hiking if people do not do such level of the training.  My case is now the both sides are balanced since I was looking into the data from the both side.   From the daily training, we can guess a reasonable pace during the hiking.   It is important to see data from hiking and see actual strength looks like.

   Especially, the hiking this year, I controlled the pace very well based on the heart rate.   Therefore, the overall strength is also controlled as well.  Without controlling the pace, the strength during hiking could be much higher which means the equivalent strength for the daily hiking would be higher as well.
