Training for a Fall 2023 Marathon

As we start approaching summer, that means it's time to start thinking about fall 2023 marathons. Many of the biggest U.S. Marathons happen in the fall – perfect as the weather starts to cool down and the humidity decreases! This year, I’m going to be in the groups of tens of thousands running them too as I train for Chicago!

How Long Do I Need to Train for a Marathon?

This one varies a lot depending on each runner’s current ability and goals. In general, somewhere between 14 and 20 weeks is best. If you have a base of 20 miles or more per week and have run a marathon before, closer to 14 weeks is absolutely long enough! If you run less per week or have never run a marathon before, I recommend longer based on experience and goals.

Below is a handy graphic using an 18-week training plan on when you need to start training for each of the major fall U.S. based marathons!

The Marathons

Wineglass Marathon

The course is fast. Very fast. Personal records tend to fall here. Beyond the chance for a PR, the speed also makes Wineglass one of the top spots to qualify for the Boston Marathon. And the early autumn scenery is stunning. These are just a few of the reasons runners love the Wineglass. Part of the reason why Wineglass has been named one of the top 10 Destination Races in the world and why runners voted it the Best Marathon in New York State in 2018 (
