In the bustling streets of contemporary London, a nervous groom-to-be finds his life pivoting on a single, impulsive decision. Dennis Doyle stands at the altar, heart pounding with doubts about commitment, pregnancy, and his own readiness for the future. When panic overtakes him, he walks away, leaving behind a trail of hurt and unanswered questions that linger long after the wedding bells have faded.

Five years later, the city’s relentless rhythm still echoes his past mistake, now amplified by the presence of his former fiancée, Libby, who has built a new life with the confident and polished Whit. Their world is a blend of everyday hustle and the looming spectacle of the Nike River Marathon, an event that promises both physical challenge and public spectacle. The marathon becomes more than a race; it offers Dennis a tangible, high‑stakes chance to demonstrate growth, bravery, and perhaps, a second shot at love.

Against this backdrop, a quirky support crew materializes— Gordon, Libby’s loyal cousin and long‑time friend, and the eccentric landlord, Mr. Ghoshdastidar, whose unconventional training methods add a layer of off‑beat humor to the narrative. Their presence injects a warm, if slightly chaotic, camaraderie, underscoring the film’s tone of heartfelt comedy where earnestness and absurdity walk side‑by‑side.

The story flirts with the universal themes of redemption, the fear of inadequacy, and the daring pursuit of personal change, all set within a lively London that feels both familiar and vibrant. With its sharp wit, tender moments, and a dash of slapstick charm, the film invites viewers to wonder whether a marathon can truly measure the distance between past failures and future possibilities, while leaving the outcome tantalizingly open.
