Village of Constantine issued the following announcement on 31.
Registration is open for the 10th annual Marquette Marathon, Boston Qualifier. The marathon and half marathon courses both have significant elevation drops, visit multiple U.P. cities, and travel through scenic wooded scenery on the Iron Ore Heritage Trail. We like to think our marathon and half marathon are run on one of the most beautiful courses in the country . . . and did we mention the elevation drops?
