Storms

Thunderstorms & lightning

If you head out

If you hear thunder, you're close enough to be at risk — head inside immediately.
Never shelter under lone trees; a car or sturdy building is safer.
Check the forecast before you leave; summer storms can build fast.

Indoor alternatives

Full indoor workout: 10 min warm-up walk, 20 min treadmill or stairs, 5 min cool-down.
Yoga or mobility session — matches a recovery day in your plan.
Bodyweight circuit: squats, lunges, planks, glute bridges (3 rounds).
Reschedule the run — one moved workout does not ruin your plan.

Never run outdoors during active lightning. Wait 30 minutes after the last thunder clap before going back out.

LetsRunNow provides general fitness education, not medical advice. Talk to your doctor before starting or changing an exercise program — especially if you have a health condition, are pregnant, are recovering from injury or illness, or have not been active recently. Extreme heat, cold, or poor air quality carry real health risks — when in doubt, move your run indoors. Read our full terms.
