Instructions
Step by Step
- Please familiarise yourself with the following instructions.
- Launch the Jundo Predictor© from the left Links Menu.
(Read the instruction first, then start it!)
- First enter the distance for the race 1. See the
How to enter a Distance section below.

- Chose a unit of distance from the drop down list.
In this example we leave it on Metres.

- Then enter the time for the race 1. See the
How to enter a Time section below.

- Enter the distance and time for the second race

- Fill in some distances that you want predicted. You do not have
to complete every distance field. Just leave a distance blank
and it will be ignored

- Press the calculate button to have the entire page processed

- See the results:

How to enter a Distance
Races distances can be entered in Metres, Kilometers, Yards, Miles,
Miles and Yards, 1/2 Marathon or marathon.
Decimal and/or Fractional input can be used for the distance.
For full and half marathon units, leave the numeric distance field blank.
When using the miles+yards unit, you must enter two distances separated by a
plus sign.
How to enter a Time
Times can be entered in a choice of formats. Use which ever you feel comfortable with!
The three formats are:
- Using h,m,s for example: 1h23m45.67s
- Using " for hours and ' for minutes: 1"23'45.67
- Using colon between the hours, minutes and seconds: 1:23:45.67
All the above are equivalent.
Time entered or displayed must be less than one day.
Using Multiple Sheets
A handy feature of Jundo Predictor is the ability to see more than one
sheet of inputs and results on the page. Up to 4 sheets of data can be viewed
side by side on the page. Going multi-sheet can be helpful for
these examples:
- You coach more than one athlete, and you wish to see each athlete,
or compare times between athletes.
- You enter each sheet with data for yourself on a different time.
For example, you have 3 sheets showing how you performed in 2003, 2005, 2006.
- You want to see on separate sheets what affect a small change to a time will have.
For example: What is the new predicted Marathon time, if your 1/2 Marathon time was run 12s faster, but 15km time was unchanged?
- You use the copy sheet feature to replicate a chosen sheet before making a small change for comparison.
System Requirements
By keeping all Jundo Predictor© calculations web based,
the service should be available to many types of computer and operating system.
Cookies may be used to enhance the operation of the site and services,
or supply feedback to help improve the website.
Certain features of the Jundo Predictor (e.g. field blanking and/or validation)
are enhanced by Javascript code. Where possible the site and the Jundo Predictor
have been written so that much of it is still possible when the Javascript is not
operating.
Simple and flexible.
The input formats for time and distance give you freedom to chose metric or imperial
units, and a variety of styles.
The prediction times are displayed in the same format as that used for the Input 1.
