"A picture tells a thousand words! So cool that the @berlinmarathon took photos of us runners along the route and I encourage all of you to zoom into our expressions," she captioned the post.
"The pain, the determination and the push to finish written all over our faces."
Amy is now back in the US and revealed on Saturday that she had gone apple picking in New York with her husband Andrew Shue, the first without their children.
"This was our first year apple picking without our kiddos, missing them, but relishing the tradition always!!!" she captioned a picture of the pair joined by pals.

She joked: "They’ll come back one day. Right?"
In a second snap, Amy and Andrew were pictured posing at the farm, with Andrew kissing his wife on the head.
"Navigating this no kid thing (you’re welcome anytime Shuebachs)," she joked, using the name she has given to their family.
The pair have four children in their blended family; Amy shares daughters Ava and Analise with her ex-husband Tim McIntosh while Andrew also has two children from a previous relationship. Amy's eldest daughter Ava, 18, is now studying at NYU's Tisch School.
Amy and Andrew's children were between the ages of three and 13 when they first got together, and the doting parents wanted to ensure that the change in their lives was positive.
They found a way to help their kids bond through making up stories about animals in their garden – which has since inspired them to write their debut children's book, Better Together.
