Hi, I was looking into applying into the Canadian Military Forces. One of the requirement is to run 2.4KM in 11mins:56secs. I have been training on a treadmill, and can achieve it at 11mins:20secs. But when I test myself outside, it's all a different story. Sure, there is the wind/bump/estimated distance factors. But is there a specific training regimen that can help me overcome my obstacles and achieve what I want? One more thing, I think my left ankle is probably the part of my leg that actually feels sore or is the weakest part in this exercise, any suggestion to make it endure better?
