Hamstring tear during intervals May 2. Then a 5k a week later + Billygoat + another 5k and it was rendered useless. Trainer and therapist said no running for a month. And also my glutes are wimpy, and will result in more hamstring injury unless they HTFU.
No problem over the winter when I'm not running. Doing lots of hamstring extensions, will see if it goes well come spring.
