Alton Half Marathon & 5K Run/Walk

20 Mar 2021 (Sat)


Join Alton Half Marathon & 5K Run/Walk

The land known as the “Riverbend Region” of southwestern Missouri — where the big, wide rivers of the Missouri, Illinois and the Mississippi come together — is the setting for the Alton Half Marathon, which is set for its annual running this year along a course that hugs the riverbank of the Mississippi.

Destacable en la ruta

From the starting line at Alton’s Riverfront Park — which lies just a few blocks from the offices of the Alton Telegraph newspaper, the race’s organizer and sponsor — runners head out on an out-and-back course that keeps them in view of the waters of the Mississippi flowing by for nearly the entire race.

Some of the race’s most scenic views are expected in the early going, when runners cross the Clark Bridge over the river and head into Missouri.

Once across the river, the route then turns onto Riverlands Way and brings runners around the edges of the Riverlands Migratory Bird Sanctuary, a 3,700-acre wetlands area and natural preserve that is home to a wide range of rare migratory birds, waterfowl and raptors throughout the year.

Once runners reach the turnaround point along Riverlands Way before reaching the intersection with Red School Road, they then head back along the route they’ve just run, and back across the bridge into Illinois for the second half of the route.

The next section unfolds as a long, out-and-back stretch, first out along Berm Highway and then back, after the turn at Lock and Dam Way, on the bike path along the levee, the Madison County Transit Confluence Trail.

Runners then meet back up with Boat Launch Road after crossing under the bridge, and then make their way back into Riverfront Park for the race finish.
