This time it’s different

Today was day 5 in my 30 day walk challenge. I was unable to get my walk in on my lunch break. Normally I would just skip it and tell myself I would just double up tomorrow. That never actually happens. So today I jumped on the treadmill and got my walk done! It’s shocking to me to see how much worse my breathing is now than it was 3 years ago. I did a 5k then, today 10 minutes was a struggle.
