Detroit Lakes runner mistakenly runs full Fargo marathon after planning for a half, finally he got a marathon medal

Mike Kohler en route to his full marathon finish.

Runners never forget crossing the finish line at their first marathon, and that will be especially true for Detroit Lakes, Minn., native Mike Kohler.

When Kohler crossed the starting line in Fargo last Saturday, he thought he was going to run 13.1 miles, his first half marathon. Six hours later, he had “mistakenly” completed his first full marathon, 26.2 miles.
