Discover the Towpath Trail on a bicycle! Take a 16-mile ride beginning at St. Helena Heritage Park, riding south to Lake Ave. for a quick break and then back to St. Helena Heritage Park. This is a group ride for more advanced riders, with a faster pace and inclines. The average speed will be 9 mph or above. Bicycling at least 35 total miles a week (including this ride) recommended. Be prepared by dressing for the weather, bringing plenty of water, and wearing a helmet. Under 18 requires a guardian.
