Because of street O-race ? I know that my legs don't like hard surface. Not trained for that.
Well yes, but that was just the tip of the iceberg. Knee injury changed my stride, I run with my toes much more these days, tough for the muscle. And no much stretching, no much strength training etc. And I am not really that young I think, that doesn't help either. I guess runs like that are asking for a trouble. But what wouldn't we do to make a video...
