I just posted an article about going from being a desk jockey to running a 5k the other day. Today, I found a similar article from active.com in my inbox. Their article is similar to mine. We both encourage you to get out and do it. Do not overdo things. There is no shame in walking. Slowly build up to the 5k distance.
I am a firm believer in getting multiple opinions and making your own decisions. It is amazing how many things work well one day and not so well the next. Read up on things and draw your own conclusions. Do your best to not come up with excuses to rest.
Acitve.com is a great place for articles. They are like the Microsoft of event management. They reign supreme but they know there a lot of options available. To stay relevant, they have an online magazine and wordpress style blog. Their blog is excellent. The articles are well written and pertain to most sports for all levels. They are a “for profit site” but I have never noticed a bias in their writing. I give them kudos for keeping the bias out. I have people send me stuff to review and it is so hard to not cheer on the little guys who are just starting out or the people who contact me.
If you are not a member of active.com, I encourage you to browse around their web site. It is a good idea to sign up for their service and have your credit card on file. Some of the events we do sell out quickly. It is good to be on record when you sign up for these events.
Note: I have no affiliation with Active.com
