The Robin Hood Festival of Running has been hailed a success after more than 13,000 people took to the streets.
Most took part in the half marathon and fun run but about 2,000 managed the full distance.
The course began and ended at the Victoria Embankment and is running through the university of Nottingham grounds for the first time.
Organisers said the new festival name reflected the diverse groups taking part and events available.
First across the line in the full marathon was Nathaniel Williams from Loughborough in just under two and half hours.
He said he had only completed half marathons before the event.
"I just gritted my teeth and ran into the wind.
"I am glad it has finished and I will have my name down for London next year - and Robin Hood of course!"
