Running Clubs, Groups, and Partners: Looking for Boston Running Partner

Training alone in the evenings at this time of the year is getting increasingly boring. Would like to find another person to run with a couple evenings afterwork, and if that works out perhaps we can hook up for a long run on one of the weekend days. My pace is average - for my fast days, I usually do 6 to 6:20 miles; Normal days - 7-7:30 a mile, and long days anywhere from 8-9 minutes a mile. Typically, I never run less than 5 miles, but I am open to change! Ideally, I would like to find someone to meet up for an easy run one night, some tempo/speed work another night, and provided we can tolerate one another for longer than 50 minutes, we can maybe get together for a longer run (10-13 miles) over the weekend
