Every time I run in P.E. (Physical Education) it seems I'm last of many. When it comes to speed I struggle but for long distance runs I'm able to last longer than most people. Specifically: the impact on my feet feels heavy.
I do the right posture too, plus I only weigh 52 kg (New Zealand measurements) so I'm not really heavy at all but I feel like my lower body is weighing me down when I try to run. More than anything I can't run for far too long as I'm low on stamina and power in strength. The only thing that helps me in competitions involving running or jumping is my determination and integrity.
