No, it isn't just you.
Making it through 26.2 miles is daunting even for professional runners such as Meghan Peyton, the 2013 U.S. champion at 20 kilometers and one of the country's top competitors at distances from one mile to 20K.
That isn't the only trait Peyton shares with the 11,628 others registered for Sunday's Twin Cities Marathon. Like them, she finds that iconic distance as irresistible as it is forbidding, leading her to again join the masses on the course from Minneapolis to St. Paul.
Sunday's race will be Peyton's third marathon, and the Richfield resident believes the lessons learned in her first two attempts have prepared her to move up from last year's ninth-place finish.
Peyton said Friday she has had to develop a patient approach to running the distance.
The Team USA Minnesota runner also adjusted her training this year, putting in longer workouts than she had in the past. She and the other elite entrants will be chasing $145,000 in prize money, along with the national titles awarded to the men's and women's winners.
"The marathon is still a little scary because it is a long way," Peyton said. "And if you don't run it correctly, like I did last year, it's a long time to suffer. But at the same time, it's a challenge — and I love a challenge.
"In a marathon, I've learned that in the first half, at least, you have to be within yourself. You have to set a pace you know you can accomplish, and then really race the last 10k. That's my goal."
