Could Boston, Chicago, and New York Become 2-Day Marathons?

The London Marathon is planning a groundbreaking two-day event in 2027, aiming to host 100,000 runners, which has sparked speculation about whether major U.S. marathons like Boston, Chicago, and New York might follow suit. This shift could revolutionize how marathons are organized, making them more accessible and inclusive. While it's still early, the idea of a two-day marathon could transform the running landscape by allowing more people to participate over a longer period, offering a fresh take on traditional marathon formats.
