Cycling enthusiasts can look forward to the 2026 edition of the Tour de France, beginning Saturday at 7 p.m. on Channel 5. The prestigious race launches with its Grand Départ in Barcelona, setting the stage for three weeks of elite competition. Riders will navigate through Catalonia toward the Pyrenees foothills before continuing through southwestern France, passing through the cycling hub of Pau and concluding Stage Seven in Bordeaux. Coverage tracks the athletes as they tackle demanding mountain climbs and sprints in pursuit of the coveted yellow jersey.

On Tuesday at 7 p.m., TLC premieres "Suddenly Amish," a documentary series examining challenges faced by the Amish community amid a sharp decline in population, attributed in part to genetic concerns from centuries of intermarriage. Bishop Vernon, a community leader, initiates an unusual experiment by inviting six outsiders to live as Amish for a month. Participants adhere to strict religious and lifestyle codes, relinquishing modern conveniences such as smartphones, social media, electricity, and indoor plumbing. They also engage in manual farm work, follow plain dress codes, and participate in traditional courtship practices.

Following immediately at 8 p.m. on Sky One and NOW, the American adaptation of the UK medical comedy "Doc Martin," titled "Best Medicine," debuts with Josh Charles in the lead role as Dr. Martin Best. Set in the coastal town of Port Wenn, Maine, the series chronicles the unorthodox doctor’s interactions with local residents. The premiere episode introduces a patient who turns blue after consuming an excessive number of blueberries, offering a blend of medical mystery and humor.

BBC One continues the second season of the sitcom "Austin" on Friday at 11:10 p.m. Ben Miller and Sally Phillips reprise their roles in a storyline following children’s author Julian, who discovers that Austin, the boy he believed to be his autistic son, is not biologically related to him. Determined to help Austin find his biological father, the group travels to Northampton, setting up fresh comedic and emotional developments.

Monday at 8 p.m., National Geographic Wild presents "Sharks Up Close with Bertie Gregory," featuring the adventurer as he explores the decline of hammerhead shark populations in Mexico’s Pacific waters. With some specimens reaching lengths of up to six meters, these iconic predators have seen their numbers fall sharply, making sightings scarce. Gregory collaborates with scientists and local experts to investigate the causes of the decline and assess whether protected marine areas can aid in their conservation.

Finally, ITVX launches a new series Sunday, continuing the story of John Grisham’s thriller "The Firm," set a decade after the events of the original novel and 1993 film. Josh Lucas returns as attorney Mitch McDeaere, now navigating life after ten years in the Federal Witness Protection Program. The plot centers on Mitch’s efforts to evade mafia threats while adjusting to a new chapter with his family. Juliette Lewis also stars in the series, adding to the dramatic tension.
