The running movement primarily occurs in one direction or plane of motion. Yet, have you ever finished a run session and experienced sore adductors (muscles on the inside of your thigh)?

That’s due to the role of the adductors in stabilising and preventing unnecessary lateral movement during the drive and recovery phase of running,  to try to keep your forward and backward movement efficient. This is accentuated when trying to run faster and often causes muscle soreness if unprepared.
