I did Tri to Win the past 2 years (http://www.melanomaresource.org/ It's a sprint distance and lots of fun, great crowd support, and great atmosphere. The riding out that way is incredible! We do routes up and around Columbia, Ellicott City, and Sykesville - lots of tough climbs out there!

As for the CWC, it's a tough ride, but definitely do-able (I've only done the century distance, so can't comment on the metric or other distances.). We've done it the past couple of years and I can't wait to do it again this year. They recently sent out an email to get people to sign up b/c registration has been slower this year than past, so if you're going to do it, sign up so they don't cancel it!! I can't believe they would though b/c it's such a popular race (not as crazy popular as the Seagull Century though.....I think b/c of the hills).
