It is an annual point-to-point Boston Marathon qualifying marathon (42.195 km/26.219 mi) race between Lévis and Quebec City, Quebec, Canada. It has been held in August every year since 1998 and currently can reach up to 12,700 participants in all of the events combined. Along with the full marathon, a half marathon, a 10 km, a 5 km and children’s events are arranged as well.
The course distinguishes itself from other races in that kilometer markers are posted in reverse order, indicating the remaining distance to the finish line. Among other things, this allows all events to start at the same time and on the same course, from the appropriate distance away from the finish line.
The race is part of a series of races that go on around Quebec City each year called “Run Quebec City”, with the SSQ Quebec City Marathon being the most well known event.
