Join us May 9, 2015 on a great ride, the Group Health Inland Empire Century (IEC). Routes skirt the Columbia and Yakima rivers - through parks and over bridges - and return to the traditional route in the Horse Heaven Hills. Ride options are from an easy 25 miles to challenging 50, 75 or 100 mile tours. All routes showcase the scenic beauty of the lower Yakima/Columbia River valley with its vineyards, wheat fields and fruit orchards.
See Sample Map and Elevation Profile.
From Columbia Park you will head east through Kennewick, across the Columbia to Pasco, then cross again to Richland, while other rides go on to Benton City. The 50 mile ride returns from Bdenton City to Richland. The 75 and 100 mile rides climb Webber Canyon Road to the green rolling wheat fields of the Horse Heaven Hills. Before descending out of the wheat fields above Prosser you can enjoy a breathtaking view of the entire lower Yakima River valley. The route then travels westward to the outskirts of Prosser and back. You return via the Old Inland Empire Highway to Benton City and join the 50 mile route back to Richland. The route to Prosser and the Old Inland Empire Highway are surrounded by vineyards and fields of hops and fruit trees.
