Even in sports, I found I hated running. I played goalie or I played volleyball, I never liked any sport that made me run. Why run now? I wanted to do something different. I happen to enjoy my current exercise routine of Zumba and spinning classes, but over the summer there are fewer spinning classes and one of my favorite instructors is dropping one of my classes. When I camp, It's hard to pack all the bikes and gear and if I do then I definitely can't bring the canoe, and so I thought running would be a great "portable" exercise routine that I can stick to on vacation.
In addition the reality is that we've all been walking since around 14 months old, our bodies are very efficient at it and we don't burn very many calories walkng.
I am happy to say day 1 of the C25K program did not kill me. I did realize that sneakers just won't work though, I picked up some proper (on sale and not custom fit) running shoes and day 2 was better on the joints, but cold air is not good for asthmatics. I had to start over but I finished day 2 eventually. Hate might be a strong word. I'm not loving running yet, but I am doing it. I still prefer Zumba, I May complete the program just to prove I can do it and never run again.
Running is harder on the joints. Running has a learning curve too, those ear buds just don't stay in like you'd expect. You need a much better sports bra for running than you do for spinning and yes, people might see you. I may or may not stick with it, I don't plan to do something I hate forever, but at least I will know I can and I will surpass my annual step goal, and for now Ill just run with it.
