Race Across the World contestant Fin has opened up about the insecurity he felt when his partner Sioned discovered his health condition.
The fifth series of the BBC One competition programme follows five pairs as they travel more than 14,000km across Asia while trying to keep under a budget of around £1,000 per person.
In the first episode, Fin and Sioned were walking in China when his blood sugar level dropped, and he explained that he has type one diabetes.
