All together now...

One way to get yourself out the door for a run is to join a group run.
Group runs offer a chance to meet new people, get in a 3-5 mile training run and enjoy some socialization afterward.
In the Greater Boston area of Massachusetts, for example, I found groups that run each week: the Somerville Road Runners' Bur-run (Mondays) out of The Burren in Davis Square; the Runfellow apparel company's run club on Tuesdays; and the Marathon Sports run club on Wednesdays in Boston, Brookline and Wellesley.
Running on local roads with a group can acclimate you to the terrain in your neighborhood -- where the flats are, and where the hills are. You'll also learn about safety precautions; the groups I looked at all stress wearing reflective clothing at night, a good idea on congested streets and sidewalks.
