Birmingham's first International Marathon will take place on Sunday 15 October - and Great Run say 6,500 people have already signed up - seven months in advance.
The 26.2 mile route will begin at the Alexander Stadium before heading through the city centre, out to Bournville, past Edgbaston Cricket Ground and Cadbury World along the way, before returning to Millennium Point.
Anyone familiar with racing in Birmingham might be pleased to hear "The Hill" has gone for good.
David Hart from Great Run says the route isn't too hilly...
But of course, David says "running is coming home", because it's not the first marathon to be held in the city. There was a marathon in Birmingham before there was one in London!
Last year, the 10k and half marathon raised £4m for charity, and hotels are expected to be sold out. David says the event will do so much for Birmingham- and it's Commonwealth Games bid.
The city has hosted 10ks and a half-marathons for years - here's a clip of one of the many previous intrepid participants crossing the finishing line.
