Jennifer Garner was all smiles and positive energy as she celebrated the final day of her 67-mile challenge in Santa Monica this week. The actress and mother of three looked super cute in her braided hair and chic athleisure wear, fully embracing the sporty mom vibe -- showing that fitness and fashion can go hand in hand!
Before lacing up for her last mile, Jennifer delivered an inspiring and heartfelt speech about what motivated her to take on the challenge in the first place. “When things feel out of control, find one thing you can do for yourself that makes you feel like you’re putting something good into the world,” she shared with the crowd. She added, “Keeping the promise to myself every day for these kids on the other side of the world has shifted something in me.”
The challenge, which Garner kicked off on her 53rd birthday to support the Save the Children organization, has clearly been a deeply personal journey for the actress.
It wasn’t just a physical test -- it ignited an emotional transformation along the way. Garner even found ways to involve her closest friends, turning the experience into a fun group effort.
Garner was later spotted joining a warm-up session with fellow participants, stretching and working out the kinks as she prepped for the final leg of her challenge.
As she completed her last mile, Jennifer didn’t just stop at the finish line -- she turned back to help a fellow runner who was struggling to finish, compassionately guiding the runner step by step until they crossed the finish line together, sharing a heartfelt hug in a moment while the crowd cheered them on.
On hand to celebrate the big moment was Jen's longtime boyfriend, John Miller, who cheered her on from the sidelines. The low-key couple has kept their relationship mostly private, but this time, John proudly stepped into the spotlight to support Jennifer in her moment of triumph.
After wrapping up the event, Jennifer and John shared a sweet celebratory kiss, sealing the day with a dose of well-deserved romance as they officially make their relationship public.
