This 3rd ride in the Base Builder seires takes you along Denver's western foothills to Chatfield State Park, then north on the Platter River Bike Path through urban industrial regions to downtown Denver. Enjoy riding this busy path with many other trail users. The riparian forst along the Platte River is still golden, but preparing for its long winter sleep. This workout is the logest in the series, lasting nearly an 100 minutes and covering 35 of beautiful Denver. Enjoy.
