Mexico City Marathon

Registration is open to all runners and typically opens in mid-February. The race has a cap of 30,000 runners and closes on August 26 or when the cap is reached, whichever comes first. Charity entries are also available through the 'Run with a Cause' program.

Yes, the race is a Boston qualifier. Keep in mind the course is not USATF certified, so check current BAA certification requirements before registering if that matters for your qualification.

The course runs between roughly 7,300 and 7,540 feet above sea level. Acclimatization is strongly recommended, especially if you are traveling from a lower elevation. Arriving a few days before race day gives your body time to adjust before you toe the line.

The point-to-point route has a modest net gain of about 213 feet and no major climbs. The challenge is altitude, not hills. The course runs on urban roads through the city from the Olympic stadium to the Zócalo.

The time limit is 6.5 hours.

Late August sits in the rainy season, so expect mild temperatures but a real chance of rain. Mornings start cool and warm through the day. Light, moisture-wicking gear is a safe bet, and a disposable layer for the corral can help if you are standing around before the gun.

Mexico City International Airport is about 5 miles from downtown. Allow around an hour by car or taxi depending on traffic. The start is at Estadio Olímpico Universitario in the south of the city, and the finish is at the Zócalo in the historic center.
