FREQUENTLY ASKED QUESTIONS
- I can't get the map to work.
If you're having problems with the map, let us know using the feedback form below. Don't forget to tell us which browser you are using, and try to be precise about what went wrong.
We are aware that a small number of people are presented with a blank map of the US, or no map at all, and are working to resolve those problems.
- Some items on the map aren't placed where they should be.
The nature of the marathon means a lot of events happen in very close proximity along a fixed route - if we plot them too precisely, they overlap and become very difficult to see clearly.
If you zoom in to the closest level, the positioning of some icons may not be precise, but the spacing stops reports disappearing from view beneath each other.
- How 'live' is this map?
New content is added to the map as soon as it becomes available - in many cases there is a short delay involved, as video, audio and images must be received and edited before being published.
- But it looks like nothing had changed.
You need to refresh the page to see updates. Some points on the map, for example image galleries, update with fresh content as the marathon progresses. In other cases, older content is removed from the map and replaced by newer content from a similar area.
- It would have been useful to see the full marathon route on this map.
We agree. This was not possible this year, but we expect to offer this in future.
