There are several TV channels that show live athletics events on a regular basis. The majority of events are on free to air channels, mainly BBC Sport (which also shows the World Athletics Championships and Olympic Games) and ITV.
You can also find some meetings shown on Eurosport. This does require a subscription but is generally includes in most sports packages such as BT Sport and Sky.
This TV schedule is updated daily and shows full details of all the live athletics on TV over the next 14 days (if any). Note that there is not always going to be live coverage every week, as it generally centres around major world and European events.
For an overview of upcoming meetings throughout the year, check the BBC Athletics Calendar.
