While training for a triathlon, Trina will first swim, then cycle and finally run. She will swim either 200, 300, 400 or 500 metres, followed by cycling 5, 9, or 13 kilometres, and finally running either 2 or 3 kilometres. How many different possible choices of training routines does Trina have?

4 x 3 x 2 = 24 possible routines.
