The One Simple Rule That Tells You When Not to Run This Winter

You’re managing to get those runs in over winter, the legs are ticking over, and then bam, a sore throat, a runny nose, and a head that feels like it’s stuffed with porridge. Right before Christmas and all! It seems to be par for the course in Ireland, where the only thing more common than drizzle is catching a dose of something.

Why Runners are Bug Magnets

Running is brilliant for long-term health, but hard training can temporarily put a dent in your immune system. Add in cold weather, crowded Christmas parties, and kids coughing like extras from a Victorian drama, and it’s no wonder half of us spend December sniffling.
