Runners will have one more chance to participate in the Run for Heroes marathon in Amherstburg this September before the event is cancelled for good.

Organizer Chris Uszynski said the run, which is a Boston marathon qualifier, is just too expensive.

"We actually import 14-and-a-half kilometres of pylons for a lane closure for the 42 kilometres, which is actually 2,000 pylons that we rent for one day out of Toronto at a cost of $10,000," he said.

Uszynski said 600 runners are registered for the marathon this year, which takes place on Sept. 21.

He said the loss is significant for runners in the region.

"It was one of those events that people around North America would look up under Boston qualifier and see Amherstburg, Ontario and would stay in Windsor and it would look at it as a destination spot," said Uszynski.

He hopes to continue organizing the half marathon, 10 km run and kids events in future years.

The pledges and donations raised from the marathon typically go to the Caregiver Support Programs at the Alzheimer Society of Windsor and Essex County.
