The Daglish is a very simple running drill.
You need something that can mark out the red spots (1-7) and something to run on.
Place out the things you use for marking in a pattern. One thing to remember is that you shouldn't place it in a circle. Everything but a circle.
And also chose how many laps you want to run just by adding or removing markings.
Choose on the spot to be No 1.
Make the persons running at No. 1 and have them sprint at full speed to No 2. Then slow down and jog point 2 through 7 and back to No 1.
Now sprint at full speed from No 1 to No2 to No 3. Jogging No 3 through No 7 and back to 1.
Sprint full speed No 1 thru No 4. Jog No 4 through No 1.
And so on. At the last lap you will sprint the whole race No 1 through No 7 and back to No 1.
