Hi all--I'm new here--I live in the US and did the couch to 5k program years ago. This month I decided to do it again and was disappointed to discover that you now have to pay for the US couch to 5k app so I decided to try out the NHS podcasts. I really like them so far! My husband and I are on week three, but I'm finding running at a high altitude (almost 8000 feet) to be very challenging. Last year we were regularly running 3 miles per run at sea level. It's going to get easier right? I hate being so out of breath.
