Just as the Tour de France enters a decisive uphill Time Trial stage at La Planche-des-Belles-Filles! And as we all know, the Time Trial was David's speciality and the Tour de France the race that inspired him, so it couldn't be a better time to release the film to the wider UK public.
You can find BBC Scotland on 115 on Freeview, YouView or SKY, 106 on Freesat and 108 on Virgin Media.
The film will screen thereafter on iPlayer for around a month.
If you watch the film, please tell us and tag us on Twitter @Timetrialfilm and let's get more people watching it.
If you are not in the UK, you or your friends can watch the film in many places online worldwide.
