Like probably most of you I normally land on my forefoot when I run, but recently I tried switching to a heel strike when I go down hill. Why? To let gravity do its work and safe energy. I have the feeling when I go FF downhill I am just using energy to try and slow myself down. I should probably mention that I only do this for steep declines and the Netherlands doesn't exactly have any mountains.
Anyone else experimenting with their strike in certain situations?
