October 2026 might be the busiest single month on the global sports calendar, packing marathon majors, world championships and international NFL football into just a few weeks.
## Endurance Sports Take Over Early October
The month opens with the Bank of America Chicago Marathon on October 11, one of the fastest courses in the world and the site of Ruth Chepngetich’s 2:09:56 world record. Just a day earlier, on October 10, the Ironman World Championship returns to a single-day format in Kailua-Kona, Hawaii, reuniting the professional men’s and women’s races for the first time since 2019.
## Cycling’s Biggest Weekend Away From Europe
That same weekend, October 10 and 11, the UCI Gravel World Championships head to Nannup, Western Australia, the first time the event has ever been held outside Europe. It follows the UCI Road World Championships in Montreal, which run from September 20 to 27 and mark the road cycling championships’ first Canadian appearance since 2003.
## Rugby League’s Month-Long Showcase
The Rugby League World Cup kicks off October 15 and runs through mid-November, spread across Australia, New Zealand and Papua New Guinea in the tournament’s most geographically ambitious edition yet.
## The NFL Goes Global
The NFL’s record nine-game international slate runs through the month too, with Paris hosting its first-ever regular-season game on October 25 and London hosting matches across two consecutive weekends earlier in the month.
