sore groin

[[email protected]]

I recently ran a race and the next day on an easy long run, my left
groin muscle started aching and got to the point where I had to walk to
finish my run. It doesn't seem to be too serious but I want to be
careful.

Two questions: how long should I wait before I try to return to
running and what alternate exercises can I do (biking, swimming, etc.)

Thanks.
