Software for time-trial race
This will run in python (only 3.X, not 2.7), a free to install programming language. Simply save the following as a file ending .py - e.g. timetrials.py. Then open IDLE3 (start menu), and open the file (Ctrl+O). Finally, press F5 to start it.

When everyone has finished, it will look something like this:

┌──────────────┬───────────────┐  
│  Con Num     │ Time H:M:S    │  
├──────────────┼───────────────┤  
│  1           │ 5:4:3.2       │
