This application enables triathletes and coaches to calculate qualification times for aspiring Great Britain Age Group triathletes.

Use the toggles towards the top of the screen to select whether your calculations are for Sprint or Standard distance triathlon and whether its for European or World Championship qualification.

Then you can use the first slider to adjust the Age Group Winner's time. Which then sets the standard for qualification in that age group at that selection race. The minimum required time is displayed on the screen. You can use the triangular buttons at either end of the sliders to fine tune the times.

Next you enter your time using the second slider and if your time is below the minimum requirement you will see a green Q, because you have met the standard. However, please bear in mind that the Age Group team managers select the team from those who have made the standard, that means that if 50 people make the standard and there are only 20 slots available, only the fastest 20 will get selected.
