Eight Go Rallying: The Road to Saigon
9pm, BBC Two
Doing it for the skids: this new reality show thrusts celebrity duos – Popworld’s Miquita Oliver and her foodie mum Andi; Martin Kemp and pop partner Shirlie; Noel Edmonds and wife Liz; plus Tinchy Stryder and Jordan “Rizzle Kicks” Stephens – into a rally challenge. Tackling a picturesque 3,000km route from Chiang Mai in northern Thailand to south Vietnam in tuned-up vintage rides presents plenty of obstacles to overcome, not least how to actually navigate without smartphones.
