Should I avoid long runs or tougher workouts during menstruation?

If you feel lousy during your period, be flexible with your training. You should not have to avoid long runs or tough workouts throughout, but listen to your body. If you’ve planned a long run, head out with no pressure to do the distance. If you don’t feel good, go shorter and tackle the long run another day.

Avoid really tough sessions when you’re feeling at your worst, but you could do some interval work. You may struggle with longer reps, but try a few shorter efforts, such as a block of easy 200m reps, so you’re not pushing too hard. If you want to include longer reps, do them to time rather than distance, to ensure you don’t overexert yourself.
