Flat Stanley Bike Ride Coalville to Echo Canyon Do you know who Flat Stanley is? Well he's flatter than a pancake and so is this ride. Meet Donna at the Coalville Courthouse and prepare to leave by 9:30 a.m. The ride is 37 miles but there is an option of an additional 15 to Henefer. Bring water, snacks and of course a helmet. There will be regrouping.
