I've done my first Parkrun and since then more 5k runs/walks using 5k+ podcast. I've had a cold which always sets off asthma...I'm walking way more than I would like, but my breathing isn't great. Do I need to push through or just take time on the couch to recover? I always find that it takes 2 or 3 weeks for the asthma to return to normal after a cold. The 5k+ podcast is pushing my natural pace so I am running faster!
