50 miles: Shop to Harwood Loops

Here is a link to a route from the shop through Davidsonville to a loop used by one of the local cycling teams as a weekly ride. All these roads are a lot of fun and I've ridden them many times.

62 miles: Columbia Triathlon + 37

Here is a Google Maps link to a route that starts at Centennial Park in Columbia and covers the whole route of the Columbia triathlon. It branches off, however, to add another long loop out through the rolling terrain up toward Woodbine and through Patuxent River State Park. I will post an update once I get the chance to ride the whole loop to verify road conditions etc.
