Hill Intervals Up Squaw Peak
July 18, 2011 7:00 pmLate this afternoon I headed out for a climb up Squaw Peak with the plan of doing some interval training during the climb. It is a bit under 4 miles with little climbing up the Provo River Trail, then part on the Highway, to reach to road up Squaw Peak. From there it is nearly a 1,800 feet climb over 4.2 miles. With a rather constant grade, it is a great place to do some hill intervals. I decided to ride as hard as I could while climbing 400 feet, then do a recovery for 200 more feet of climbing. I would be able to repeat this for a total our three intervals before reaching the summit.
For a year now I have been on a beta-blocker for blood pressure. It has been like a year in cycling prison because this stuff really lowers your heart rate, really slowing you down. I was also taking another medication in addition, and had to cut both doses down to keep from going too low on my blood pressure. During my 4 month follow-up visit to the Cardiologist last week, she decided to take me off one of the medications and offered a chance to decide. That was an easy decision, so I finally stopped taking the beta blocker.
One of the reasons why I was originally put on the beta blocker was that my blood pressure went very high during a stress test. Everyone’s blood pressure rises during a stress test, but mine went much higher than usual. So after stopping the beta blocker I wanted to get some blood pressure readings during intense climbing so I took a wrist blood pressure monitor with me.
Here is the data from the average of the hill repeats I have done. On my latest workout I wanted to get my blood pressure, so I had to come to a stop and stand on the ground, otherwise I would get an error on the blood pressure monitor. I was able to get stopped rather quickly at the end of the interval. The reading should be fairly indicative because you can see the heart rate on the blood pressure monitor was close to my my maximum heart rate during the interval. It has been along time since I was able to take my heart rate up above 170 bpm. I was happy that the blood pressure readings were so reasonable during these intervals. I pulled out my data from 3 years ago when I did a similar hill interval workouts up Squaw Peak and Thomas Grade. You can see my climbing speed declined since then, even though I was pushing my heart rate higher. However in 2008 I was in top form and was training for both the Everest Challenge and the Furnace Creek 508.

This shows graphically the vertical climbing speed (VAM) for each of the hill repeats I have done. The vertical climbing speed is measured in meters per hour. It will change depending on the grade and typically for every one percent increase in average gradient increases VAM by 50. Since Thomas Grade and Squaw Peak average grade is within 1%, they can be compared directly. Improvements would show an increasing VAM and a decreasing average heart rate. My data shows the opposite.

When I reached the intersection, I noticed a sign that said Mt Madona road was closed. I could see that it was open to residents. Hum, I thought. I am a resident of Gilroy and a cyclist too boot so I figure it was okay to bike up the road.
