Then he will fly to Boston that afternoon to run his 11th Boston marathon on Monday, Columbus Day.
"It's a challenge," he said. "It brings me to a level I've never been before, and I like that."
The opportunity to run two of the biggest marathons in the U.S. on consecutive days is a rarity. The pandemic forced the delay of Boston's marathon, which is normally held on a Monday in April.
Many runners have been forced to choose one or the other, but some are taking advantage of the chance to do both.
"I thought this is a once in a life time experience, and as a runner I gotta go for it," said Jake Greenburg, who is also running both races.
Some elite athletes are trying to make some marathon history doing the double. Aaron Pike plans to race the wheelchair marathon in Chicago and then give whatever strength he has left on the hilly Boston course the next day.
After canceling last year's in-person race, Bank of America marathon director Carey Pinkowski said he's happy to be back. This will be the first major marathon in the U.S. since the start of the pandemic. Boston in the second.
"It's a unique experience and a challenge, and we're gonna celebrate that," Pinkowski said.
While organizers are busy setting up the hospitality tents and other areas for runners after the race, those doing the double have no time for that. They have to race to the airport to catch a flight.
