Traditional Volkssport event so you can start anytime between 8am and noon, to finish by 3pm. There will be a group walk starting at 10am if you want to walk a 10k with the group. Trail is rated 2C. It's only a 400 ft elevation gain overall, so it's a 2in C, because of some steep stairs in the 10K part. 5K is a 2B.
Walk on sidewalks through neighborhoods down to Dash Point State Park and continue down on dirt park trails to the beach. The 5k returns well short of the beach and any difficult terrain. The 10k will encounter two sets of steps cut into the bank and backed by logs. Some are a little steep. This is a good walk to have shoes with good tread and a walking stick for support on the steps. The route will be dry. Once down off the hill you'll go across a bridge with "Lincoln Log" looking supports, then down a trail with a series of boardwalks until you reach the parking lot and then to the beach and restrooms. The uphill return is fairly gradual, but there are benches to sit and enjoy the scenery if you're tired. The park is forest and shady. The neighborhood to the from the park will likely be sunny. Wear a hat and use sunscreen.
Dogs welcome on leash with owners cleanup, but not in buildings.
