Open to both runners and walkers, Oregon’s Helvetia Half Marathon & 10K takes runners on hilly, challenging course on rolling paved country roads along the northern rim of the Tualatin Valley in the West Hills of the Portland area.
From the starting line at the Hillsboro Stadium athletic complex, just off Bennett Street, runners follow the first mile of the course westward along Bennett, 235th Avenue and Huffman Street, and turn again northward onto Brookwood Parkway.
The course follows a counter-clockwise loop route up along Helvetia before following Jackson Quarry southward all the way to West Union Road, where runners turn left and head south back toward Helvetia. From there, runners continue down Helvetia before retracing the steps they took during the first mile toward the finish at the stadium, where the runners and walkers cross the finish line on the football field’s 30-yard line.
Along the way, participants will run across gravel surfaces on portions of the route, though most of the race is run on paved surfaces.
The first two to three miles and the last four to five miles of the race route are mostly fast and flat, with a few gently rolling hills here and there.
In between are the race’s most significant hills, as the course jumps from about 200 feet above sea level around the mile 3 marker to over 450 feet between mile markers 4 and 5.

You really need to find a way to keep one lane open during this race. Too much farm activity along this route that often can’t be put off. Cattle still need to be tended, horses fed, hay moved, fields cultivated, and farm workers need to get to work. Farming doesn’t get the morning off. Please!
@patemmerson You tell them! One lane would let local businesses and employees get to work on time and not impede their business! Sometimes it’s 15-30 minute wait just to get to work!!!
