Liz,
2 months ago I joined a running club for the first time, I have been running more off than on for around 4 years, and have not done any serious running for 2years. I now run between 6-8 miles in approx. 1hr twice a week. I am usually the slowest, but I am working on that, they take it in turns to run with me, so they get some speed work in, they give me plenty of encouragement and advice, so no I don't think they would laugh you off the streets.
