Is it ok to run before bedtime?

It's OK but it may: Cause insomnia. Watch a movie while your are exercising and get double the fun!

Exercise: Exercise regularly but not in late evening or it may be hard to sleep.

No: should not exercise within 4 hours of bedtime as it may interfere with sleep.

Not before bed.: While running is an excellent form of cardiovascular exercise, running before bed will activate your body at a time when you would prefer to wind down and go to sleep. In general, regular exercise has been shown to improve sleep habits. I generally recommend people run first thing in the morning, gaining energy from fat stores more than ingested carbohydrates.
