Exercise-induced vasculitis—also called golfer’s rash, Disney rash, or hiker’s rash—is a harmless condition where red or purple rashes appear on the legs after long walks or exercise in hot weather. It happens when blood pools in the lower limbs, causing small vessels to become inflamed. The rash usually clears within about 10 days with rest, leg elevation, cooling, and hydration.
It’s important to distinguish it from more serious conditions like cellulitis, folliculitis, meningitis, sepsis, or measles, which require medical care. If you feel unwell, have fever, or the rash spreads quickly, seek medical attention immediately.
