The reason I started looking into barefoot running was the reason that most of us do, and that's injury prevention. Historically I have tried running; I've tried training for the London marathon, I've tried running 10k, but the result was always the same. Bad knees, tight IT bands, and eventually injury. In the end, I just gave up. That was until I read about barefoot running.
Before changing to a barefoot running style, I went to Vivo Barefoot headquarters to have my gait analysed. I ran on a treadmill barefoot and the guys checked the way I run. They claim that everyone is designed to run and it is only due to cushioned running trainers that we end up getting injured.
The main struggle I had with barefoot running was the impact on my calves. Changing to a forefoot strike puts a lot more pressure on your calf muscles and they start to ache a lot. Like anything, you need to build up slowly. I did build up my training and I got faster and a much stronger runner. But it was time to welcome a new running injury, shin splints. You can read more about that on this blog post.
So after building up working through the issues has been changed in worth it? Completely.Remember, changing running style will not happen overnight. This is a long, slow process.
