Race Across the World
Sunday, BBC2, 8pm
As series two begins, cameras follow contestants as they embark on an epic and adrenaline-fuelled adventure, trekking into the unknown without gadgets or many of the things we take for granted. The journey will see these five pairs racing from the top to bottom of Latin America. They will trek from from Mexico City to the most southernly city in the world, Ushuaia in Argentina. With no smartphones, internet access and credit cards, the only cash they carry will be equivalent of a one-way airfare. Episode one sees the teams set off from Mexico City, the largest Spanish-speaking city in the world. Throughout the race they must pass through seven checkpoints to reach their final destination, beginning with Copan Ruinas in Honduras.

The Boys in Green
Monday, RTÉ One, 9.35pm
Fans are getting decidedly jittery as Ireland prepare to face Slovakia on March 26th in a last-gasp playoff to qualify for Euro 2020. What better way to calm the nerves than with a big, honeyed spoonful of football nostalgia? This two-part sports doc series sets the controls on the time machine straight for Ireland's golden era of football, when the Boys in Green made their first foray onto the global arena, spurring fans to join up with Jack's Army and follow the squad to Italy, the US and other far-flung places. Between 1986 and 1995, the revitalised Republic of Ireland team gave the country an almighty lift, and (probably) helped to bring the Celtic Tiger into being. All the big moments from that historic period are here, including Packie Bonner's famous penalty save against Romania in Italia 1990, Ray Houghton scoring the winning goal against Italy in the 1994 World Cup . . . I could go on, but I suspect this series will tell the story a lot better than I can. Our guides on this trip through time include Tony Cascarino, John Aldridge, Mick McCarthy, Ronnie Whelan, David O'Leary, Jason McAteer, Kevin Sheedy and Stephen Staunton

Herstory: Ireland's Epic Women
Monday, RTÉ One, 8.30pm

Contributors include Anne Maher, artistic director of Ballet Ireland; Anna Meadmore of the Royal Ballet School; and Dr Victoria O’Brien, dance historian.

Miriam's Big Fat Adventure
Monday/Tuesday, BBC2, 9pm
Miriam Margolyes loves her life but hates her body. She's been fat (a word she doesn't shy away from using) for as long as she can remember, but at 78, she feels the time to do anything about it is running out. However, she's far from alone as, despite societal pressure to be thin and the slew of information about healthy diets, Britain is more overweight than ever. So Margolyes sets out to learn more about the impact of obesity. She begins by meeting Gemma, who has checked into a weight-loss bootcamp where she's subjected to a calorie-restricted diet and five hours of exercise a day. However, blogger Bethany takes a different approach as she argues that body positivity is better than yo-yo diets and being miserable about your size.

Random Acts as Gaeilge
Tuesday, TG4, 8pm

From downward-facing madras to pop-up Gaeltachts, from Luas women to loose translations, Random Acts as Gaeilge takesa whistle stop tour of the Irish language along with the views of some well-known faces, including Stephen Fry and Ronan O’Gara. There’s a generational collide when Snapchat star James Kavanagh boards the Luas at Ranelagh and meets none other than Doireann Ní Bhriain, broadcaster, linguist, and Voice of the Luas, with insightful, educational, and hilarious results. Belfast-based Caoimhe Ní Chathail snaps regularly as Gaeilge, and through her snaps the show explores Belfast and meet other people who are using their Gaeilge daily. Na Cnocadóirí, founded in 2003, is a hiking and hillwalking group that uses Irish as the main means of communication among members. And acclaimed Dublin alt-rock group Delorentos go behind the scenes as they record a track, as Gaeilge, for this year’s Seachtain na Gaeilge Ceol.

Mrs Fletcher
Tuesday, Sky Comedy, 10.15pm

So, your only son has gone off to college, leaving you all alone in a big, empty house. What do you do? Make like Tom Cruise in Risky Business and dance around in your jocks and socks to the music of Bob Seger? How about look up the number of the local embroidery club in the hopes of filling all those empty days ahead? Kathryn Hahn stars as the titular empty-nester faced with the dilemma of what to do with her newfound freedom. (We suspect it won’t involve needlework.) Meanwhile, her son, a popular jock in high school, is out of his comfort zone and lost at sea in the complexities of social media. This HBO series promises to explore themes of gender, sexuality, parenthood, online etiquette and, inevitably, internet porn.

Five Guys a Week
Tuesday, Channel 4, 9.15pm
Never let it be said that C4 doesn't want to help the people find love – it's already brought the world Naked Attraction, First Dates and Flirty Dancing. The idea behind Five Guys a Week is that a singleton gets the chance to trial five live-in boyfriends over the course of five days. That may sound like a more sensible way to get to know someone than performing a dance routine with them or seeing their exposed body parts, but the twist is that all of them will be moving in at the same time. In the first episode focuses on marketing consultant Amy (34). Among the guys she will trial are country singer-songwriter Scott, debonair stuntman Michael, international fraud investigator Christian, and local government consultant Glenn, who fears he's less exciting than the competition.

Breeders
Thursday, Sky One, 10pm

Martin Freeman is one of the lucky actors who has escaped the Hobbit’s Curse, whereby anyone who plays one of JRR Tolkein’s diminutive characters can’t get arrested afterwards. It helped Freeman that he moved on to a superb role in the Netflix series Fargo, and now in this new 10-part series about the trials and travails of modern parenthood. Breeders addresses the big parental paradox: is it possible to love your children to death while also wanting to kill them? Parents Paul and Ally (Freeman and Daisy Haggard) struggle to bring up their two children without strangling them or – worse – not sending them to the right school. In the opening episode, Paul is up against something even more challenging than stealing a dragon’s treasure without waking him up: getting the kids to go the f**k to sleep.

However, he is believed to have been responsible for the deaths of more than 200 people. This documentary reveals the string of mistakes that led to Shipman's arrest. One of them was establishing a pattern and drawing attention to himself. Often, his victims were found fully dressed and sitting up – unusual for elderly patients who he claimed had been unwell in the weeks beforehand, while his lack of computer skills also led to his downfall.
