I am not a runner, but have always loved biking! I like that it is low impact. We are lucky in St. Louis because there are so many great trails to ride.
Matt and I love to bike the Katy Trail. Biking is a great way to get exercise and spend time together. :) Last weekend we celebrated our anniversary in Herman, MO and brought our bikes along. We rode a new section of the Katy Trail in Rhineland. The Katy Trail is 240 miles long- so many areas to explore, lucky us!
