South Mountain

My comment last Thursday that I'm not in good form got me wondering just how bad my fitness is these days. So far this year I've accumulated a couple of notable failures, the first being not getting to the top of Browns Peak in April and the second being failing the Hour Challenge on the 2012 LMI course with prolific JEC commenter and super-running-streaker Bobby et al. But just how out of shape am I?

Yesterday I sought to answer that question with my litmus test for fitness here in Phoenix: the South Mountain time trial. It's a 1200ft climb up the smooth asphalt of San Juan and Summit Roads through a Sonoran landscape to the mass of TV towers that adorn the United States' biggest city park.

There's an official South Mountain time trial race that takes place every year in May. I've never done it; every year I've either been out of town or too uncaring. But from what I hear, it's a well run event that doesn't cost much and is a lot of fun. It's also a short course. It starts at the turn-off onto Summit Rd and finishes at the top. My SoMo time trial starts at the bathrooms a mile-and-a-half further down San Juan, which adds five minutes of a rolling climb to the course.

Yesterday, by relying on the previous weekend's three-night stay in high-elevation Colorado along with a few hard rides to and from work during the workweek that followed, I mustered all my available strength and finished SoMo in 28:13. That's a good time for me. It's probably in my all-time top ten.

Though at first I was happy with that result and optimistically concluded I'm not in bad form, a sober night's rest—metaphorically, not literally—got me thinking otherwise. That is, I am in bad form, but my performance was comparably good because bad form makes me work harder. Whereas, when in good form, I've got the hustle of a pro baseball player who just signed an eight-year deal.

Yesterday I biked up South Mountain with my heart in my throat, beating about 180 times a minute until the end, where SoMo cruelly has its steepest grades and my heart rate spiked higher than what's theoretically possible, as according to the (obsolete) heuristic that one's max heart rate is 220 minus age. For as long as I've had an HR monitor, I've never sustained as high a heart rate for as long a time while on the bike; my usual half-hour all-out effort heart rate is in the range of 170-175bpm.

So now I'm not sure what to think, but it goes something along the lines of: who cares?

you could have saved time and energy with apathy prior to your investigative journey up south mtn.

Anonymous— There's a saying in the software industry that “A few hours of planning can save you weeks of coding.” But apathy can save you those hours of planning.

JEC: I think the answer to your question is: Bobby Wein Seriously, this post is fantastic, I hung on each detail -- the idea of measuring the level of self punishment, as impacted by your pride (and how you feel that day) is fun to think about. Nice effort, both on the ride and on the post.

Question: You mentioned "probably in my top 10 all time," how many times have you done the JEC time trail try on South Mountain?

Bobby et al.— I'm happy you appreciate the details in this post. When I wrote it, I wasn't sure if anyone would care about the subject beyond a one-sentence summary—if that much.

I like details too. I especially like pro-cycling articles where the pros talk about their own physiology, such as their heart rate on a hard climb or how many liters of water they drank during a six-hour race. That's not trivia to me; it's the nitty-gritty of racing.

How many times have I been up South Mountain? Maybe fifty times. Maybe more. I consider any result above 30:00 to be terrible and any result below 29:00 to be OK.
