Give yourself a try.

Granted the 68 degree weather two days prior is now replaced with subfreezing temps, but it was still worth the effort. It was the annual Shamrock Shuffle 8k race. The world's largest according to them! It was my first "race," a few years ago and that experience kicked off many others that allow both fitness and fundraising.
There are many people who don't give themselves credit for having the stamina or ability to run a race or climb a building. Just give it a try and surprise yourself the way I did back then. And if you are one who has done it, then you know what I am prattling on about. You meet new people, raise money for worthy causes and,depending on the race,you can get an upclose tour of cities and buildings. I mean, it's not every day you get to run down the middle of Michigan Avenue or past the famous Chicago Theater, right? So get on out there and plan on having some fun, even when there is still snow on the ground.

1) Race time! There were so many people lined-up to race, it took 25 mins before I made it past the Start sign which is up there somewhere.
