Pain, anguish, determination - all present in just the first few hours of the tough Longest Day event.
The third instalment of the police-led Cactus programme finished in an eight-hour endurance event on Saturday featuring an array of mental and physical challenges.
We started with a run up Mount Ngongotaha at about 5.30am - again, but for the first time during the programme we went all the way to the top.
Some judged we ran close to 30km during the day and I wouldn't doubt it.
The students carried equipment - and sometimes each other - up the mountain before moving on to the second challenge at Blue Lake.
