Over ten thousand runners woke up early Sunday ready to run the 31st Medtronic Twin Cities Marathon.
According to CBS Minnesota, the race began at 8 a.m. at the Metrodome in downtown Minneapolis. The marathon will take runners around the Chain of Lakes and will end at the St. Paul capitol.
Approximately 12,000 people are participating, and marathon organizers expect over 300,000 spectators.
It is likely that more than 40 percent of the finishers will be women, as more and more women are participating in marathons in recent years. Among marathoners in their 20s, women will outnumber women, the Pioneer Press reported.
This pattern has been seen throughout the country, with the results echoed by marathons in Boston, Chicago, Philadelphia, and more.
The Pioneer Press said that this increased participation is "part of the evolution of the sport, from a competition reserved for serious runners to something the masses could enjoy."
