Question: Can I Eat or Drink Dairy Products Before a Run?
I've heard that dairy products can cause cramping during runs. Is that true? Should I avoid dairy products before running?
Answer: If you're lactose intolerant, you may experience cramping or other digestive issues if you consume dairy products before a run. But most people shouldn't have a problem with them, as long as you make sure you're not eating closer than 1 1/2 to two hours before a run.

If you do experience GI distress or runner's trots after consuming dairy products, check with your doctor to see if you might be lactose intolerant.
