The Most Popular Loneliest Half-Marathon

I just finished the first Xperiathon race logging 13.1 miles with my iPhone.  Participants in this race start at the same time all over the world.  It was a pleasant run here in Missouri.

Even though I was alone, waking up at 5am on the Saturday after Thanksgiving, I had a good time.  I took a few pictures and even a couple video clips.

For some of the pictures I set my phone down, set a timer, ran up a little bit, then ran back for the phone.  Being a self-supported race I had to carry all my hydration and nutrition, I was the race photographer, race planner and race official.  I even cheered myself on when I needed some motivation.  A long run like this always includes long prayer time.  Me and God, lots to talk about.

About 8 miles into it, I thought it would be cool to capture a thought or two.

Since I was race director, the route went by a few landmarks, Waffle House and my friends Michael and Rhonda’s house.

At about mile 11, I had a hankering to record another video clip.  This time, I can tell the glucose levels are getting low…

Santa met me at mile 12…

I enjoyed the last few ounces of water at my virtual finish line.  No one was there.  Made it home before everyone woke up.  A morning of solitude, prayer and running.

Awesome.

Nerd Level Data Crunching

One or two of you may be interested in the tech behind the scenes…here we go.

I had 2 GPS units going.  A Garmin Forerunner 305 watch and an iPhone 4 running Mapmyrun.

The iPhone was for posting purposes for the race.  The watch maprunwas for lap time management.  I would periodically walk to tweak the pace.  This prevented me from going into the red zone (90% MHR) too soon.  I found this technique to work great when I’m not fully trained for a race.

I mapped the route the night before using mapmyrun.com

You needed to start the race with 30 minutes, before or after, 12:00 CET (Central European Time).  I started with 3 minutes to spare.

The route elevation profile was generated from GPS data from the Garmin.  I was lucky that the route ended on a down slope.  Worked out well.

My favorite part of doing a run like is is watching the heart rate data.  I wear a Garmin monitor while running (and have since the early 90’s).  Below you can see my pace and heart rate during each mile of the run.  I did well pacing at the mid to upper 11’s but somewhere in mile 11 the physiology was not there.  I notice at mile 5 my average heart rate goes up and stays there.  I take this as my anabolic threshold, happening at about 44 minutes.  The other ceiling I call my training ceiling happened this a drop in output (or an increase in pace).  This occurs at mile 11.

The problem with data is you can go on and on.  This feels like a good place to stop.
