Tell us your Robin Hood Marathon stories
The Robin Hood Marathon, in Nottingham, will be held for the 31st time on Sunday 11 September.
This year the full marathon route has been slightly changed but will still start and finish alongside the River Trent at Victoria Embankment.
There is coverage of the East Midlands' biggest mass participation event live on BBC Radio Nottingham.

New for 2011
This year competitors will not have to run around the Holme Pierrepont section as much as they have in previous years, and instead will run a longer stretch on Holme Lane.
The route will take entrants past many of Nottingham's historical landmarks including the Robin Hood statue outside Nottingham Castle.
Runners will also pass Wollaton Hall, where scenes from the new Batman film were filmed.
Entries to the half and full marathons, as well as the mini marathon, are still open. You can enter here.
