Ian Mackay of Agnew, center, prepares to lead a group of wheelchair, bicyclists, runners and others on a portion of Sea-to-Sound, a three-day, 74-mile multi-modal group ride along a section of the Waterfront Trail in Port Angeles on Saturday.

The excursion, which followed numerous portions of the Olympic Discovery from west of Lake Crescent to the Larry Scott Trail in Jefferson County, ended Sunday.

It was organized through Ian’s Ride, a nonprofit organization the advocates outdoor accessibility for all.
