About Pace

Have you ever asked yourself the question "Did I go out too fast?" or what it means to "hit the wall" or why the pacemakers don't often go on to win races?

Whatever your rating as an athlete, these questions come mind—not usually while attempting to cover a great distance a in a short time, but certainly sometime afterwards. Then begins the quest for assistance to achieve a better performance. Having a trainer or coach, mental or physical, affords you long term assistance, while using a pacemaker or pacesetter is a temporary luxury. Mass participation offers advantages like distraction from negative thoughts, and involvement results in encouragement and company. You recognize, and become familiar with, the applicable variables: distance "shorten the distance"; time "take less time"; cadence "use less leg turnover"; wind "run with the wind"; elevation "go downhill"; drafting "get in behind the biggest object going in the same direction", not to go into weather, diet, lifecycles and other topics that go beyond the scope of a pace chart. This leaves the solitary time trial as the ultimate challenge.

Any way, a good performance beats a bad one, and while all effort contributes to the final outcome, initial effort needs to be judged carefully to realize the best outcome. Consistent pace is therefore desirable in competition.

Velocity

km/h

For example (using the calculator above): input 2 hours and 20 miles. It will display your pace and velocity. The accumulator also confirms 2 hours are 120 minutes or 7200 seconds, and 20 miles are 32km or 0.76 of a marathon or 35200 yards or 160 furlong. Add 10km and the accumulator comes up with a marathon or 26 miles or 42km.

You probably have an old running diary, scraps of paper, printed results from competitions, marathon results downloads, etc. (records of your times and distances). The motivation for transferring this information to the format shown below can, I believe, be found by putting data from a couple of your performances through the File Parser, rendering a chart, and instantly revealing the character (the green line in SVG) of your performance.

How to use the File Parser

  1. Start by looking at the sample file bhh7.xml
  2. Generate a file by pressing one of the buttons below the table
  3. Mark and copy the file contents, paste into your text editor, and save as a plain text file with the appropriate extension
    1. Text Chart bhh7.txt for typewriters and line printers
      • Print to your typewriter, line-printer, and even to image-capable printers using a monospaced font
      • Part of a rotated coloured chart with split line drawn in
        bhh7.txt rotated and coloured with split line drawn in
    2. Graphic bhh7.svg will execute in most browsers
      • An SVG file rendered by Adobe SVG Renderer 3.0
        bhh7.svg rendered by Adobe SVG Renderer 3.0
    3. Table bhh7.html with pace calculations done by the parser
      • The parser table
        The parser table
    4. Database-friendly comma separated value file bhh7.csv (time and pedometer)

        Data tabulated in 2 blocks: each with splits and laps
    5. Event information bhh7.xml alone
  4. Fetch a copy of pchart.zip to work on your system
  5. Edit the xml file, or generate a new file, insert your data, save it to a new name (e.g. racename.xml), and open it in your browser
  6. Step through bhh7.xml to further familiarize yourself with XML
