The JP Morgan Corporate Challenge is running back to its roots with a 2018 May start date.
The race had been held in late May or early June since 1991, with the exception of last year when it was moved to July.
Director of Communications for the race Alan Tieuli said that’s because they really wanted to get the race into downtown Rochester.
"It was an important move for the Mayor. Important as Rochester was revitalizing its downtown. Important as more businesses are there. We wanted to really become a focal point for the community by moving down there."
While the event still drew large crowds, Tieuli said they saw a drop in last year’s numbers.
"We lost approximately 3,000 participants. Largely from public schools and university who had made up a good percentage of our participants in the past."
The race course has also been updated - the starting line will now be at Plymouth Avenue with stretches on Main Street and ending near Frontier Field.
Organizers are hoping a capacity crowd of 10,000 participants will run this year.
The race will kick off at 7pm on Tuesday May 22nd. It’s the 28th year of the event.
