It was a freak accident. I was leading off on the 4x1, and my blocks weren't nailed in. They shot backwards, but my spikes got stuck to the blocks, and while I was trying to shoot forward, the blocks (and my right leg) got shot back, and the pull happened. It also didn't help that I kept trying to go through with it all season (it was the first race of the first meet of the year.) It's excruciatiing to long jump, but I want to sweep my events at league this year so I will grind it out for the last meet and then rest.
