Ivanka Trump, 36, had an exhausting weekend, running the Army 10-Miler race in Washington DC.
The race is held every year and sponsored by the US Army, seeing thousands of civilians and military running in teams.
Amongst the thousands was Ivanka, who ran the race with her husband, Jared Kushner.
To mark the occasion, she posted a series of sweaty shots to her Instagram page, along with some intimate family snaps.
In the collection of four photos, Ivanka can be seen beaming as she completed the race with her husband.
She wore a tight black tank top, black cap and leggings, a stark contrast to her usual polished high heel-clad looks.
Showing off a more playful side to Donald Trump’s daughter, one photo showed her holding onto her medal while pouting at the camera.
She also posed with other racegoers including army personnel.
Proud of her achievements, Ivanka wrote: “Just finished the Army 10-Miler!
“Army Strong! Hooah! (we spent much of the race behind a guy wearing a shirt that said ‘if you can read this, I’m not last.’”
Other images in the collage showed touching moments between the couple and their children.
One shows Ivanka kissing and hugging her son Joseph, 4, as she ran the race.
Another shows Jared taking a break from running to high-five their daughter Arabella, 7.
The sweet shots attracted varied attention from her 4.5 million followers, gaining almost 90,000 likes.
One praised Ivanka, writing: “Wow great job you two!”, many others called the couple’s efforts “phenomenal” and congratulated them.
Her casual vest and leggings running ensemble couldn’t be more different from the £2,000 coat she wore last week.
Ivanka Trump took a trip to Mooresville in North Carolina last Wednesday, touring the NASCAR Technical Institute.
The itinerary also saw the businesswoman visit Hyde Park Baptist Church in Robeson County, which is currently serving as a relief site for hundreds of people affected by Hurricane Florence.
During the day, the fashion designer and author was pictured wearing a khaki Michael Kors trench coat.
The item fell just below her knees and cinched at her waist with the help of a belt. The designer number retails at around £2,000 ($2,595).
