Twin Cities Marathon canceled at last minute due to record heat

The Twin Cities Marathon was canceled just hours before start time due to extreme heat.
Record high temperatures near 90°F were forecast for race day in Minneapolis/St. Paul.
Organizers prioritized safety in deciding to cancel the races, which drew 20,000 entrants.
Some runners still completed the marathon route unofficially despite the cancellation.
This was only the second cancellation in the history of the Twin Cities Marathon.
